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.

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 ...

VLT transit and occultation photometry for the bloated planet CoRoT-1b [PDF]

, 2009
peer reviewedWe present VLT eclipse photometry for the giant planet CoRoT-1b. We observed a transit in the R-band filter and an occultation in a narrow filter centered on 2.09 microns.
