Volans-Carina: A New 90 Myr Old Stellar Association at 85 pc
Jonathan Gagné, Jacqueline K. Faherty, Eric E. Mamajek
We present a characterization of the new Volans-Carina Association (VCA) of stars near the Galactic plane (b ~ -10 deg) at a distance of ~75-100 pc, previously identified as group…
WEIRD: Wide-orbit Exoplanet search with InfraRed Direct imaging
Frédérique Baron, Étienne Artigau, Julien Rameau +9
We report results from the Wide-orbit Exoplanet search with InfraRed Direct imaging (WEIRD), a survey designed to search for Jupiter-like companions on very wide orbits (1000 to 50…
Understanding Fundamental Properties and Atmospheric Features of Subdwarfs via a Case Study of SDSS J125637.13-022452.4
Eileen C. Gonzales, Jacqueline K. Faherty, Jonathan Gagné +2
We present the distance-calibrated spectral energy distribution (SED) of the sdL3.5 subdwarf SDSS J125637.13-022452.4 (J1256-0224) using its Gaia parallax and its resultant bolomet…
A Young Ultramassive White Dwarf in the AB Doradus Moving Group
Jonathan Gagné, Gilles Fontaine, Amélie Simon +1
We use Gaia DR2 kinematic data and white dwarf evolutionary models to determine that the young and ultramassive white dwarf GD 50 is a likely member of the AB Doradus moving group.…
BANYAN. XIII. A First Look at Nearby Young Associations with Gaia Data Release 2
Jonathan Gagné, Jacqueline K. Faherty
In this paper we examine the nearest 100 pc entries in the data release 2 of Gaia to identify previously unrecognized candidate members in young associations. We analyze 695 952 st…
A Gaia DR2 Confirmation that 2MASS J12074836-3900043 is a Member of the TW Hya Association
Jonathan Gagné, Eileen C. Gonzales, Jacqueline K. Faherty
We use new data from Gaia DR2 to confirm that the young L1 candidate member of the TW Hya association (TWA) is now a bona fide member with a model-dependent mass estimate of ~1…
A Pre-Gaia DR2 Survey for Nearby M Dwarfs in Young Associations
Jonathan Gagné, Jacqueline K. Faherty, Gilles Fontaine
In this research note we identify 130 new M-type candidate members of young associations with the BANYAN tool and recently published trigonometric distances from RECONS and URA…
BANYAN. XII. New Members of Nearby Young Associations from Gaia-Tycho Data
Jonathan Gagné, Olivier Roy-Loubier, Jacqueline K. Faherty +2
We present a search for stellar members of young associations within 150 pc of the Sun based on Gaia-Tycho and an updated version of the BANYAN software to determine Bayesian m…
Precise Near-Infrared Radial Velocities with iSHELL
Bryson Cale, Peter Plavchan, Jonathan Gagné +3
We present a possible NASA key project using the iSHELL near-infrared high-resolution echelle spectrograph on the NASA Infrared Telescope Facility for precise radial velocity follo…
Fundamental Properties of Co-Moving Stars observed by
John J. Bochanski, Jacqueline K. Faherty, Jonathan Gagné +5
We have estimated fundamental parameters for a sample of co-moving stars observed by and identified by Oh et al. (2017). We matched the observations to the 2MASS and…
BANYAN. XI. The BANYAN multivariate Bayesian algorithm to identify members of young associations within 150 pc
Jonathan Gagné, Eric E. Mamajek, Lison Malo +8
BANYAN is a new Bayesian algorithm to identify members of young stellar associations within 150 pc of the Sun. It includes 27 young associations with ages in the range ~1-800 M…
2MASS J13243553+6358281 is an Early T-Type Planetary-Mass Object in the AB Doradus Moving Group
Jonathan Gagné, Katelyn N. Allers, Christopher A. Theissen +3
We present new radial velocity and trigonometric parallax measurements indicating that the unusually red and photometrically variable T2 dwarf 2MASS J13243553+6358281 is a member o…
