Condensation Clouds in Substellar Atmospheres with Virga

Natasha E. Batalha, Caoimhe M. Rooney, Channon Visscher +14

Here we present an open-source cloud model for substellar atmospheres, called Virga. The Virga-v0 series has already been widely adopted in the literature. It is written in Python…

JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the Pictoris disk with NIRCam and MIRI

Isabel Rebollido, Christopher C. Stark, Jens Kammerer +21

We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~m provi…

Near-Infrared Transmission Spectroscopy of HAT-P-18b with NIRISS: Disentangling Planetary and Stellar Features in the Era of JWST

Marylou Fournier-Tondreau, Ryan J. MacDonald, Michael Radica +24

The JWST Early Release Observations (ERO) included a NIRISS/SOSS (0.6-2.8m) transit of the 850K Saturn-mass exoplanet HAT-P-18b. Initial analysis of these data…

JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU

Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch +33

The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5 um at moderate spectral resolution (R~2,700) and thereby bet…

JWST-TST DREAMS: Quartz Clouds in the Atmosphere of WASP-17b

David Grant, Nikole K. Lewis, Hannah R. Wakeford +39

Clouds are prevalent in many of the exoplanet atmospheres that have been observed to date. For transiting exoplanets, we know if clouds are present because they mute spectral featu…

Mass Derivation of planets K2-21b and K2-21c from Transit Timing Variations

Maryame El Moutamid, Kevin B. Stevenson, Billy Quarles +5

While various indirect methods are used to detect exoplanets, one of the most effective and accurate methods is the transit method, which measures the brightness of a given star fo…
