Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab

Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33

Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…

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…

Nautilus Space Observatory: The Evolution of Planets and their Atmospheres

Ilaria Pascucci, Noah Tuchow, Yifan Zhou +11

We are just beginning to explore the billion-year evolution from nascent planets in disks to mature planetary systems. Recent discoveries hint at demographic and atmospheric differ…

KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c

Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16

While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…
