JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b

Mathilde Mâlin, Kimberly Ward-Duong, Sierra L. Grant +21

Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to dispers…

The mid-infrared spectrum of Pictoris b. First VLTI/MATISSE interferometric observations of an exoplanet

M. Houllé, F. Millour, P. Berio +46

Few spectra of directly-imaged exoplanets have been obtained in the mid-infrared (> 3 m). This region is particularly rich in molecular spectral signatures, whose measurements…

Large-amplitude Variability Driven by Giant Dust Storms on a Planetary-mass Companion

Xianyu Tan, Xi Zhang, Mark S. Marley +17

Large-amplitude variations are commonly observed in the atmospheres of directly imaged exoplanets and brown dwarfs. VHS 1256B, the most variable known planet-mass object, exhibits…

Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B

Q. Kral, J. Wang, J. Kammerer +130

Direct astrometric detection of exomoons remains unexplored. This study presents the first application of high-precision astrometry to search for exomoons around substellar compani…

Discovery of a Debris Disk Around TWA 20

Skyler Palatnick, Maxwell A. Millar-Blanchaer, Jingwen Zhang +20

We report the discovery of a debris disk surrounding the M3 star, TWA 20, revealed by JWST coronagraphic observations using the Near-infrared Camera (NIRCam). With reference-star d…

Constraints on the Orbit of the Young Substellar Companion GQ Lup B from High-Resolution Spectroscopy and VLTI/GRAVITY Astrometry

Vidya Venkatesan, S. Blunt, J. J. Wang +99

Understanding the orbits of giant planets is critical for testing planet formation models, particularly at wide separations greater than 10 au where traditional core accretion beco…
