Eclipse Timing of the Eccentric Planet HD 80606b with JWST: Constraints on a Second Planet and other Dynamical Effects

Charles Beichman, Billy Quarles, B. J. Fulton +6

A variety of effects can perturb the orbital properties of single planets in close orbits around their host stars. HD80606 b is a highly eccentric (=0.93) exoplanet orbiting its…

Nautilus Space Observatory: Unveiling the Diversity and Origin of Sub-Neptunes with the Nautilus Space Observatory

Luis Welbanks, Kylie E. Hall, Julien de Wit +10

Sub-Neptunes are the most common class of planets in the Galaxy, yet they have no Solar System analog and remain poorly understood as a population. JWST observations have revealed…

Mapping Stellar Heterogeneities with the Nautilus Space Observatory

Adina D. Feinstein, Jeff Valenti, Julien de Wit +9

Stellar photospheric heterogeneities, such as starspots and faculae, are a fundamental limitation for exoplanet transmission spectroscopy. Inhomogeneous surfaces can imprint wavele…

Nautilus: Fast Time-Resolved Spectroscopy of GKM Stellar Flares and Their Implications for Planetary Habitability

Chia-Lung Lin, Adina D. Feinstein, Jeff Valenti +10

Low-mass GKM dwarfs are prime targets for finding habitable-zone Earth-sized planets, but their frequent flares, especially on M~dwarfs, can strongly affect planetary atmospheres t…

J0404+1112: A 3-Hour Eclipsing White Dwarf-Brown Dwarf Probing Multiple Atmospheric Regimes

J. de Wit, R. Alonso, B. V. Rackham +19

White dwarf-brown dwarf (WD+BD) binaries are rare laboratories for probing both substellar survival through post-main-sequence evolution and the physics of strongly irradiated atmo…

A gem system with a lava world and a habitable zone sub-Neptune orbiting TOI-1752

A. Peláez-Torres, F. J. Pozuelos, G. Morello +47

The Transiting Exoplanet Survey Satellite (TESS) has delivered a large number of transiting planet candidates around nearby stars by identifying periodic decreases in stellar brigh…
