Design of the Life Signature Detection Polarimeter LSDpol
Christoph U. Keller, Frans Snik, C. H. Lucas Patty +11
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials s…
A medium-resolution spectrum of the exoplanet HIP 65426 b
Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +18
Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detectio…
LOUPE: Observing Earth from the Moon to prepare for detecting life on Earth-like exoplanets
Dora Klindžić, Daphne M. Stam, Frans Snik +6
LOUPE, the Lunar Observatory for Unresolved Polarimetry of the Earth, is a small, robust spectro-polarimeter with a mission to observe the Earth as an exoplanet. Detecting Earth-li…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) V. Detection of sodium on the bloated super-Neptune WASP-166b
J. V. Seidel, D. Ehrenreich, V. Bourrier +17
Planet formation processes or evolution mechanisms are surmised to be at the origin of the hot Neptune desert. Studying exoplanets currently living within or at the edge of this de…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) IV. A spectral inventory of atoms and molecules in the high-resolution transmission spectrum of WASP-121 b
H. J. Hoeijmakers, J. V. Seidel, L. Pino +22
Aims: We survey the transmission spectrum of WASP-121 b for line-absorption by metals and molecules at high spectral resolution, and elaborate on existing interpretations of the op…
Hunt for Starspots in HARPS Spectra of G and K Stars
Brett M. Morris, H. Jens Hoeijmakers, Daniel Kitzmann +1
We present a method for detecting starspots on cool stars using the cross-correlation function (CCF) of high resolution molecular spectral templates applied to archival high-resolu…
Information content of JWST-NIRSPEC transmission spectra of warm Neptunes
Andrea Guzmán-Mesa, Daniel Kitzmann, Chloe Fisher +7
Warm Neptunes offer a rich opportunity for understanding exo-atmospheric chemistry. With the upcoming James Webb Space Telescope (JWST), there is a need to elucidate the balance be…
Mass loss rate and local thermodynamic state of KELT-9 b thermosphere from the hydrogen Balmer series
A. Wyttenbach, P. Mollière, D. Ehrenreich +12
KELT-9 b, the hottest known exoplanet with K, is the archetype of a new planet class known as ultra-hot Jupiters. These exoplanets are presumed to have an atmosphere do…
High-resolution Transmission Spectroscopy of MASCARA-2 b with EXPRES
H. Jens Hoeijmakers, Samuel H. C. Cabot, Lily Zhao +10
We report detections of atomic species in the atmosphere of MASCARA-2 b, using the first transit observations obtained with the newly commissioned EXPRES spectrograph. EXPRES is a…
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M super-Earth and two warm 14.7 and 10.2-M sub-Neptunes
D. Hidalgo, E. Pallé, R. Alonso +57
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC\,249893012, a G8\,IV-V evolved star ($M_\star…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) III. Atmospheric structure of the misaligned ultra-hot Jupiter WASP-121b
V. Bourrier, D. Ehrenreich, M. Lendl +21
Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present…
