MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4-5 m. I. Photometric analysis of Pic b, HIP 65426 b, PZ Tel B and HD 206893 B

Tomas Stolker, Sascha P. Quanz, Kamen O. Todorov +6

Directly imaged planets and substellar companions are key targets for the characterization of self-luminous atmospheres. Their photometric appearance at 4-5 m is sensitive to th…

First Resolved Scattered-Light Images of Four Debris Disks in Scorpius-Centaurus with the Gemini Planet Imager

Justin Hom, Jennifer Patience, Thomas M. Esposito +57

We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB Association with high-contrast imaging and…

TOI-132 b: A short-period planet in the Neptune desert transiting a G-type star

Matías R. Díaz, James S. Jenkins, Davide Gandolfi +45

The Neptune desert is a feature seen in the radius-mass-period plane, whereby a notable dearth of short period, Neptune-like planets is found. Here we report the {\it TESS} discove…

Measuring the atomic composition of planetary building blocks

M. K. McClure, C. Dominik, M. Kama

Volatile molecules are critical to terrestrial planetary habitability, yet difficult to observe directly where planets form at the midplanes of protoplanetary disks. It is unclear…

Beyond the exoplanet mass-radius relation

S. Ulmer-Moll, N. C. Santos, P. Figueira +2

Mass and radius are two fundamental properties for characterising exoplanets, but only for a relatively small fraction of exoplanets are they both available. Mass is often derived…

The potassium absorption on HD189733b and HD209458b

Engin Keles, Matthias Mallonn, Carolina von Essen +9

In this work, we investigate the potassium excess absorption around 7699A of the exoplanets HD189733b and HD209458b. For this purpose, we used high spectral resolution transit obse…
