TOI-199 b: A Well-characterized 100 day Transiting Warm Giant Planet with TTVs Seen from Antarctica
The Astronomical Journal, 2023 We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using ground-based photometry from ASTEP in Antarctica including a full 6.5 hr ...

Kepler Bonus: Light Curves of Kepler Background Sources
The Astronomical Journal, 2023 NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

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 ...

Non-detection of Contamination by Stellar Activity in the Spitzer Transit Light Curves of TRAPPIST-1 [PDF]
, 2018 We apply the transit light curve self-contamination technique of Morris et al. (2018) to search for the effect of stellar activity on the transits of the ultracool dwarf TRAPPIST-1 with 2018 Spitzer photometry.

Multiwavelength transit observations of the candidate disintegrating planetesimals orbiting WD 1145+017 [PDF]
, 2015 We present multiwavelength, ground-based follow-up photometry of the white dwarf WD 1145+017, which has recently been suggested to be orbited by up to six or more short-period, low-mass, disintegrating planetesimals.

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 ...
