MagAO-X and HST High-contrast Imaging of the AS209 Disk at Hα
The Astronomical Journal, 2023 The detection of emission lines associated with accretion processes is a direct method for studying how and where gas giant planets form, how young planets interact with their natal protoplanetary disk, and how volatile delivery to their atmosphere takes

Detecting Multiplanetary Systems with Gravitational Microlensing and the Roman Space Telescope
The Astronomical Journal, 2023 It is plausible that most of the Stars in the Milky Way Galaxy, like the Sun, consist of planetary systems, instead of a single planet. Out of the estimately discovered 3980 planet-hosting stars, about 860 of them are known to be multiplanetary systems ...

Three Warm Jupiters around Solar-analog Stars Detected with TESS
The Astronomical Journal, 2023 We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the TESS space mission and confirmed through ground-based photometry and radial velocity measurements taken at La Silla observatory with FEROS.

Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...
