Separating flare and secondary atmospheric signals with RADYN modeling of near-infrared JWST transmission spectroscopy observations of TRAPPIST-1
Ward S. Howard, Adam F. Kowalski, Michael Radica +10
Although TRAPPIST-1's temperate planets have the highest transmission signals of any known system, flares contaminate 50-70% of transits at the 1000 ppm level, far above 100 ppm se…
TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc
Adalyn Gibson, Meredith A. MacGregor, Ward S. Howard +9
We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling c…
Flares on TRAPPIST-1 reveal the spectrum of magnetic features on its surface
Valeriy Vasilyev, Nadiia Kostogryz, Alexander I. Shapiro +11
TRAPPIST-1 is an M8 dwarf hosting seven known exoplanets and is currently one of the most frequently observed targets of the James Webb Space Telescope (JWST). However, it is notor…
Hubble's Multi-Year Search for Exospheres in the TRAPPIST-1 System Reveals Frequent Microflares
David Berardo, Julien de Wit, Michael Gillon +14
Ly- observations provide a powerful probe of stellar activity and atmospheric escape in exoplanetary systems. We present here an analysis of 104 HST/STIS orbits monitoring the T…
