CAFE follow-up of TESS hot Jupiter candidates left behind: I. Five newly confirmed planets and a false positive

J. Lillo-Box, C. Cifuentes, O. Balsalobre-Ruza +56

Hot Jupiters are key targets for understanding planet formation, migration, and atmospheres. Yet, most ground-based follow-up resources for the TESS mission are focused on confirmi…

The HST/WFC3 Transmission Spectrum of AU Mic b Part I: An Atmosphere Obscured by Contamination and Systematics

William C. Waalkes, Peter Gao, Elisabeth Newton +10

Young sub-Neptune progenitors around M dwarfs offer an excellent opportunity to probe the formation of their abundant, older cousins. At 20 Myr and only 9.7 pc away, AU Mic b…

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…

A Scalable Path to Astrometric Exomoon Discoveries with the Nautilus Space Observatory

Kevin Wagner, Sumin Seung, Dániel Apai +15

Moons orbiting exoplanets (exomoons) can be detected through the reflex motion they impart to their host planet, which is recoverable in relative star-planet astrometric time serie…

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…

The Pan-Pacific Planet Search -- IX. A menagerie of companions orbiting evolved stars

Robert A. Wittenmyer, Alexander Venner, Tyler Fairnington +22

We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey…
