Observations of planetary winds and outflows

Leonardo A. Dos Santos

We have recently hit the milestone of 5,000 exoplanets discovered. In stark contrast with the Solar System, most of the exoplanets we know to date orbit extremely close to their ho…

Water and an escaping helium tail detected in the hazy and methane-depleted atmosphere of HAT-P-18b from JWST NIRISS/SOSS

Guangwei Fu, Néstor Espinoza, David K. Sing +11

JWST is here. The early release observation program (ERO) provides us with the first look at the scientific data and the spectral capabilities. One of the targets from ERO is HAT-P…

The Hubble PanCET program: Emission spectrum of hot Jupiter HAT-P-41b

Guangwei Fu, David K. Sing, Drake Deming +6

We present the most complete emission spectrum for inflated hot Jupiter HAT-P-41b combining new HST WFC/G141 spectrum from the Hubble Panchromatic Comparative Exoplanet Treasury (P…

The Maximum Mass-Loss Efficiency for a Photoionization-Driven Isothermal Parker Wind

Shreyas Vissapragada, Heather A. Knutson, Leonardo A. dos Santos +2

Observations of present-day mass-loss rates for close-in transiting exoplanets provide a crucial check on models of planetary evolution. One common approach is to model the planeta…

Radial velocity precision of ESPRESSO through the analysis of the solar twin HIP 11915

Yuri Netto, Diego Lorenzo-Oliveira, Jorge Meléndez +4

Different stellar phenomena affect radial velocities (RVs), causing variations large enough to make it difficult to identify planet signals from the stellar variability. RV variati…

On-sky commissioning of MAROON-X: A new precision radial velocity spectrograph for Gemini North

A. Seifahrt, J. L. Bean, J. Stürmer +10

MAROON-X is a fiber-fed, red-optical, high precision radial velocity spectrograph recently commissioned at the Gemini North telescope on Mauna Kea, Hawai'i. With a resolving power…
