HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
The panchromatic JWST dayside spectrum of WASP-121 b reveals a refractory-rich formation
K. Angelique Kahle, Paul Mollière, Laura Kreidberg +16
One path to understand how planets form is to link their present-day atmospheric composition to predictions from planet formation models. For the hottest planets, the abundances of…
Machine-learning clustering of close-in exoplanet populations: links to pebble accretion
Yi Duann, Anders Johansen, Haiyang S. Wang +1
Close-in exoplanets exhibit a wide range of orbital architectures and physical properties shaped by both formation conditions and migration processes. Although population-synthesis…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
Exocomets of Pictoris II: Two dynamical families of exocomets simulated with REBOUND
K. P. Jaworska, H. J. Hoeijmakers
We investigate the dynamical evolution of particles in the Pic system to determine likely formation pathways to the present-day observed exocomet populations. We aim to relate…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period
Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148
We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…
