This study examines the forces which shaped the main character--Tess Durbeyfield--in Hardy's novel in terms of the effects which her alcoholic family had upon her mental and emotional potential and which ultimately become the determining factors in her self-destruction. Using the elements and patterns set forth in the literature regarding the dynamics of the alcoholic family, I attempt to show that Hardy's novel may best be understood as the story of a woman whose life and destiny are controlled by the consequences of her father's alcoholism. This interpretation seems to account best for many elements of the novel, such as Tess's destruction, and provides a rich appreciation of Hardy's technique and vision.

La majorité des exoplanètes connues à ce jour ont été découvertes par la méthode du transit, qui infère indirectement l’existence de tels objets, si l’alignement le permet, en mesurant la baisse temporaire et répétée de la brillance d’une étoile lors du passage d’une exoplanète devant celle-ci. La recherche de biosignatures, donc de vie, dans l’atmosphère d’une exoplanète est désormais le principal objectif dans ce domaine d’études, et pour maintes raisons, celles de taille de moins d’approximativement deux rayons terrestres autour d’étoiles naines rouges sont particulièrement convoitées. Afin de connaître davantage de tels systèmes dans le voisinage solaire et dans toutes les régions du ciel, le Transiting Exoplanet Survey Satellite (TESS) fut lancé en avril 2018. Le grand échantillonnage de 21'' par pixel des caméras à bord de TESS résulte fréquemment à une contamination des données des étoiles d’intérêt montrant un signal prometteur de transit, par le flux d’autres étoiles à proximité. Lorsque l’une de ces sources contaminantes est une étoile binaire à éclipses, phénomène astrophysique pouvant mimer un transit, la détection constitue très souvent un événement faux positif. Ainsi, de nouvelles observations photométriques et spectroscopiques sont généralement requises pour identifier les véritables exoplanètes. Ce mémoire présente les résultats du suivi photométrique de neuf candidates exoplanètes identifiées par TESS à l’Observatoire du Mont-Mégantic avec la caméra Planètes Extra-Solaires en Transit et Occultations (PESTO). Une routine d’ajustement de courbe de transit développée durant cette maîtrise procure une estimation de certains paramètres physiques (rayons, demi-grand axe et inclinaison) des candidates. Parmi celles-ci, TOI 1452.01 ressort du lot, car cette probable exoplanète d’environ deux rayons terrestres orbite dans la zone habitable de son hôte naine rouge, c’est-à-dire à une distance permettant la présence d’eau liquide à sa surface. / The majority of the exoplanets known to date have been discovered using the transit method, which indirectly infers the existence of such objects by measuring a temporary and repeated drop in the brightness of a star when, for the right alignement, an exoplanet passes in front of it. The search for biosignatures, thus life, in an exoplanet atmosphere is now the main objective in this field of study, and for several reasons, planets with a radius less than approximately two Earth radii around red dwarfs are particularly targeted. With the goal of finding more such systems in the solar neighbourhood and in all regions of the sky, the Transiting Exoplanet Survey Satellite (TESS) was launched in April 2018. The large image sampling of 21'' per pixel of the cameras on board TESS often results in data contamination of stars showing promising transit signal, by the flux of nearby stars. If one of these contaminating sources happens to be an eclipsing binary, an astrophysical phenomenon able to mimic a transit, the detection is most likely a false positive event. Thus, follow-up observations in photometry and in spectroscopy are generally required to identify the genuine exoplanets. This thesis presents the results of a photometric monitoring campaign at the Observatoire du Mont-Mégantic with the Planètes Extra-Solaires en Transit et Occultations (PESTO) camera of nine exoplanet candidates identified by TESS. A transit curve fitting routine developed during this master’s provides an estimation for certain physical parameters (radius, semi-major axis and inclination) of these candidates. Among them, TOI 1452.01 stands out, because this probable exoplanet has an estimated radius close to two Earth radii, in addition to being located within the habitable zone of its red dwarf host, i.e. at a distance allowing the presence of liquid water on its surface.

The dissertation is based on Hardy's representation of Victorian working-class women's experience, exemplified by the heroine of Tess of the D'Urbervilles (1891), in the radically gendered nineteenth-century society. Physical mobility as metaphor and metonymy in the novel stands for the transgression and subversion of patriarchal influence and is revealed as having a complex significance in relation to gender distinction. Hardy subverts Victorian norms of femininity through Tess's movements from one physical space to another in her struggle for freedom and autonomy. However, Hardy's inability to transcend completely the conventions of his society is apparent in the way Tess is literally destroyed in her quest for autonomy, respect and contentment. A study of the novel reveals Tess as a victim of the wearing and destructive impact of social and economic realities that Hardy does not adequately questioned. Finally, the novel follows the conventional realist pattern where the transgressive heroine is punished in the end. / English Studies / M.A. (English)

In Thomas Hardy's Tess of the d'Urbervilles a relationship exists between the symbolical sacrifice of Tess at Stonehenge and her association with fertility, ritual, and mythic cycles of seasonal death and rebirth. Because Hardy associates Tess with fertility, reproductive power, and seasonal change, she personifies nature and closely resembles the earth mother goddess Demeter. Ritual is evident in her participation in the May-Day club revel, in her intended suicide under the mistletoe, and in her manner of killing Alec d1Urberville. Myth cycle culminates with a fertility ritual in the powerful sacrificial incident at Stonehenge, for, although Tess physically dies at Wintoncester, she symbolically dies at Stonehenge. Following her execution, the significance of her symbolic death at Stonehenge becomes apparent in her rebirth in 'Liza-Lu, In the Demeter-Persephone myth, two anthropomorphic entities, the mother and the maiden, enact the single phenomenon of organic nature--the principle of life seen in the seasonal growth of vegetation. Tess, then, as mother symbolizes the end of the old year's crops, while 'Liza-Lu as maiden signifies the fructification of Tess's seed in the burgeoning fertility of the new year. By being reborn in 'Liza-Lu, Tess thus completes the mythic pattern of seasonal changes.

Aims. The aim of this work is to investigate any presence of transit timing variations (TTVs) in a sample of observed targets that has light curves in both K2 mission data and TESS mission data.  Methods. The original sample utilised here was one from the doctoral thesis of D. Soto (2020) with candidates from K2 data. Cross-referencing for corresponding light curves in TESS was done with a customised Python script created for the purposes of this work, automating the process of obtaining light curves using only one mission ID. A transit search was performed on the light curves of each mission separately with the Python software package OpenTS. The candidates with transits in both light curves were subjected to a TTV search using the Python software package PyTTV. The PyTTV software utilises both mission light curves in creating a joint light curve.  Results. Orbital periods, Porb, and transit center times, t0, for 30 targets were updated using joint light curves from the K2 and TESS missions. Seventeen of these systems are found to have non-linear trends in their transit times. These also have constraints for the periods and amplitudes of the TTVs.  The disposition distribution of the 30 systems is that 19 candidates are unregistered candidates, ten are registered planetary candidates or TOIs and eight are registered known planets.  Conclusions. Out of the reference sample by D. Soto (2020) consisting of 564 targets, 257 targets had a corresponding TESS light curve. Out of the 257 targets, a new sample of 45 targets was contrived through a transit search where they all show distinct transits in both missions light curves. Out of these, fifteen targets were not suitable for a TTV search. A final sample of 30 targets are presented, with seventeen targets showing signs of TTVs and thirteen targets showing a linear trend. The parameters of orbital period and transit centre times are updated for all 30 final candidates. Seventeen candidates are shown to have variations in the transit times and are presented with diagnostics. The candidates with transit timing variations should be further investigated for potential validation or follow-up observations. The unregistered candidates as well as the planetary candidates and TOIs should be considered for follow-up observations or similar validation, to confirm or discard a planetary status.
