Tighter constraints on the atmosphere of GJ 436 b from combined high-resolution CARMENES and CRIRES observations

A. Peláez-Torres, A. Sánchez-López, L. Nortmann +23

We aim to study the atmospheric properties of the warm Neptune GJ 436 b by combining a set of five transit events observed with the CARMENES spectrograph with one transit from CRIR…

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…

Grain growth in protoplanetary disks in the Upper Scorpius revealed by millimeter-wave spectral indices

Tau Bito, Akimasa Kataoka, Takahiro Ueda +3

The measurement of dust size from millimeter-wavelength spectra provides direct constraints on grain growth in protoplanetary disks. The spectral indices between 0.88 mm and 2.9 mm…

Upper limits on atmospheric abundances of KELT-11b and WASP-69b from a retrieval approach

F. Lesjak, L. Nortmann, D. Cont +18

WASP-69b and KELT-11b are two low-density hot Jupiters, which are expected to show strong atmospheric features in their transmission spectra. Such features offer valuable insights…

Starlight-driven flared-staircase geometry in radiation hydrodynamic models of protoplanetary disks

Prakruti Sudarshan, Mario Flock, Alexandros Ziampras +2

Protoplanetary disks observed in millimeter continuum and scattered light show a variety of substructures. Various physical processes in the disk could trigger such features -- one…

Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map

Ryan C. Challener, Megan Weiner Mansfield, Patricio E. Cubillos +33

Highly-irradiated giant exoplanets known as "ultra-hot Jupiters" are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, la…
