Broadband 12-26 GHz Radio Radiation Reveals Evidence for Micro-flares on AU Mic

Isaiah I. Tristan, Rachel A. Osten, Yuta Notsu +2

We present sequential 12-18 and 18-26 GHz radio-band (, ) VLA observations of the 22 Myr dM1e star AU Mic. We detect two flares and two marginal events over a total of 3 con…

ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution

Allison Youngblood, Kevin France, Brian Fleming +37

The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…

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…
