A Blind Search for Transit Depth Variability with TESS
The Astronomical Journal, 2023 The phenomenon of transit depth variability offers a pathway through which processes such as exoplanet atmospheric activity and orbital dynamics can be studied.

The effects of star spots on transit photometry [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWe have undertaken an observational program to photometrically monitor several transiting planet host stars. The Rabus et al. result for TrES-1 showed the dramatic effects star spots can have on transit photometry. We will investigate the effects of spots on transit light curves and estimates of planetary radii.

TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf
The Astrophysical Journal Letters, 2023 We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 ( V = 12.6, T = 11.9), first detected using observations from the Transiting Exoplanet Survey Satellite (TESS) by the TESS Single Transit ...

Exoplanet transit spectro-photometry with SOFIA [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWe present the prospects of observing extrasolar planets with the Stratospheric Observatory for Infrared Astronomy (SOFIA). Our analysis shows that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and\break eclipses will be feasible with SOFIA's instrumentation, especially with the ...

Transit origami: a method to coherently fold exomoon transits in time series photometry [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT One of the simplest ways to identify an exoplanetary transit is to phase fold a photometric time series upon a trial period – leading to a coherent stack when using the correct value. Such phase-folded transits have become a standard data visualization in modern transit discovery papers.

No Conclusive Evidence for Transits of Proxima b in MOST Photometry [PDF]
The Astronomical Journal, 2017 Abstract The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be ...

Constraining the oblateness of transiting planets with photometry and spectroscopy [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle ingress and egress features in photometric transit light curves, we investigate the effect of oblateness on the spectroscopic Rossiter–McLaughlin (RM) signals. We found that

TOI-5205b: A Short-period Jovian Planet Transiting a Mid-M Dwarf
The Astronomical Journal, 2023 We present the discovery of TOI-5205b, a transiting Jovian planet orbiting a solar metallicity M4V star, which was discovered using Transiting Exoplanet Survey Satellite photometry and then confirmed using a combination of precise radial velocities ...
