Titan is unique among the icy satellites in that it has a thick atmosphere, stable surficial bodies of liquid, and a precipitation system that promotes interactions between the two. Although Titan’s surface conditions are typically assumed to be ab

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 t

On the Masses, Age, and Architecture of the VHS J1256-1257AB b System
Autor: Trent J Dupuy, Michael C Liu, Elise L Evans, William M J Best, Logan A Pearce, Aniket Sanghi, Mark W Phillips, Daniella C Bardalez Gagliuffi
VHS J1256$-$1257 AB is an ultracool dwarf binary that hosts a wide-separation planetary-mass companion that is a key target of the {\sl JWST} Exoplanet Early Release Science (ERS) program. Using Keck adaptive optics imaging and aperture masking inter

True masses of the long-period companions to HD 92987 and HD 221420 from Hipparcos-Gaia astrometry
Autor: Logan A. Pearce, Andrew Vanderburg, Alexander Venner
The extensive timespan of modern radial velocity surveys has made the discovery of long-period substellar companions more common in recent years, however measuring the true masses of these objects remains challenging. Astrometry from the Gaia mission

Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC 257605131, Gaia DR2 4844691297067063424). TOI 451 is a member of the

An Edge-On Orbit for the Eccentric Long-Period Planet HR 5183 b
Autor: Alexander Venner, Logan A Pearce, Andrew Vanderburg
The long-period giant planet HR 5183 b has one of the most extreme orbits among exoplanets known to date, and represents a test for models of their dynamical evolution. In this work we use Hipparcos-Gaia astrometry to measure the orbital inclination

Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During the red giant phase, any close-orbiting planets will be engulfed by th
