Simulations and technology development for time-domain astronomy : TESS and InGaAs detectors
… The Kepler mission has identified thousands of exoplanet systems with the transit technique, allowing the first statistical analyses of the exoplanet population. The upcoming Transiting Exoplanet Survey Satellite (TESS) mission will complement Kepler by identifying the brightest transiting …

Identifying and Analyzing Multi-Star Systems Among TESS Planetary Candidates Using Gaia
<p>Exoplanets represent a young, rapidly advancing subfield of astrophysics where much is still unknown. It is therefore important to analyze trends among their parameters to learn more about these systems. More complexity is added to these systems with the presence of additional stellar …

High-resolution studies of protoplanetary disks
… stars, most of these constituting known exoplanet systems, were examined for circumstellar material using the Adaptive Optics instrument ADONIS at La Silla Observatory (Chile). With the new Adaptive Optics system NAOS-CONICA at Paranal (Chile) we tested the technique of Polarimetric …

Toward detection and characterization of exoplanetary magnetic fields via low frequency radio observation
… radio emission from extrasolar planets ( exoplanets). The first is a novel approach using 'big data' and computer aided discovery tools to mine radio survey images for faint radio emission from the location of nearby stars. The flexible approach described in this thesis produced upper …

Binary star systems and extrasolar planets
… and our own solar system. Over half of star systems contain more than one stellar component. Despite this, binary stars have often been avoided by programs searching for planets. Discovery of giant planets in compact binary systems would indirectly probe the timescales of planet formation, an …

A New Era of Observational Capability at Ritter Observatory: Spectropolarimetry from Exoplanets to Circumstellar Disks and Beyond
… potential polarimetric variability in exoplanet systems. In particular we focused on the system HD189733, as there was previous observational work in the literature claiming both a detection and non-detection at different optical wavelengths. The goal was to investigate this system with …

Exoplanetary Systems in Technicolor
… surpasses 5000, our ability to characterize exoplanets has equally advanced in the era of high precision photometry afforded by instruments such as the James Webb Space Telescope. With increased precision, longer baselines of observation, and access to multi-instrument data sets, the study of …

Towards Generalized Characterization of Exoplanet Atmospheres with Transit Spectroscopy
The field of exoplanetary sciences has grown from an era of detection to one of characterization. To date, over 4000 exoplanets have been discovered and over 50 of them have been observed with primary transit spectroscopy methods. The current population of characterized exoplanets spans a wide …
