A Near-Infrared Spectral Library of Very Young Brown Dwarfs and Planetary-Mass Objects in the Orion Nebula Cluster
Elena Manjavacas, Mario Gennaro, Sarah Betti +3
Age-benchmark brown dwarfs' and planetary-mass objects' spectroscopy is key to characterize substellar evolution. In this paper we present the JHK medium resolution (R~3000) spectr…
JWST-TST High Contrast: Spectroscopic Characterization of the Benchmark Brown Dwarf HD 19467 B with the NIRSpec Integral Field Spectrograph
Kielan K. W. Hoch, Christopher A. Theissen, Travis S. Barman +14
We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering JWST GTO program to obtain moderate resolution spectra (R2,700, 3…
HST Survey of the Orion Nebula Cluster in ACS/Visible and WFC3/IR Bands. IV. A Bayesian multi-wavelength study of stellar parameters in the ONC
Giovanni M. Strampelli, Massimo Robberto, Laurent Pueyo +4
We have performed a comprehensive study of the Orion Nebula Cluster (ONC) combining the photometric data obtained by the two \textit{HST} Treasury programs that targeted this regio…
Insight into the Formation of Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the Pic Moving Group Member HD 181327
Henrique Reggiani, Jhon Yana Galarza, Kevin C. Schlaufman +5
It has been suggested that Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star Pic and therefore the planet'…
The Carina High-Contrast Imaging Project for massive Stars (CHIPS) I. Methodology and proof of concept on QZ Car ( HD93206)
A. Rainot, M. Reggiani, H. Sana +13
Massive stars like company. However, low-mass companions have remained extremely difficult to detect at angular separations () smaller than 1" (~1000-3000 au considering typical…
Reconnaissance of the HR 8799 Exosolar System II: Astrometry and Orbital Motion
L. Pueyo, R. Soummer, J. Hoffmann +30
We present an analysis of the orbital motion of the four sub-stellar objects orbiting HR8799. Our study relies on the published astrometric history of this system augmented with an…
