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…

JWST COMPASS Program: The 3--5m transmission spectrum of LTT 1445 A b

Natasha E. Batalha, Nicole Wallack, Tyler Gordon +16

The search for an atmosphere on the closest rocky M dwarf planet, LTT 1445 A b, has been the subject of intense investigation from both the ground and space. Here, we present the f…
