Revealing the substellar population of IC 1396: A spectroscopic survey of brown dwarfs in the region
Belinda Damian, Jessy Jose, Aleks Scholz +7
We present a new spectroscopic view of the brown dwarf population in the young star-forming region IC 1396 and investigate the impact of environment on low-mass star formation. We…
Ultracool Dwarfs Observed with the Spitzer Infrared Spectrograph. I. An Accurate Look at the L-to-T Transition at 300 Myr from Optical through Mid-infrared Spectrophotometry
Genaro Suárez, Stanimir Metchev, Sandy K. Leggett +2
We present IRS 5--14 m spectra and 16 m and 22 m photometry of the T2.5 companion to the 300 Myr-old G0V star HN Peg. We incorporate previous 0.8--5 m o…
Close companions around young stars
Marina Kounkel, Kevin Covey, Maxwell Moe +26
Multiplicity is a fundamental property that is set early during stellar lifetimes, and it is a stringent probe of the physics of star formation. The distribution of close companion…
System IMF of the 25 Ori Group from Planetary-Mass Objects to Intermediate/High-Mass Stars
Genaro Suárez, Juan José Downes, Carlos Román-Zúñiga +4
The stellar initial mass function (IMF) is an essential input for many astrophysical studies but only in a few cases it has been determined over the whole cluster mass range, limit…
Kinematic identification of young nearby moving groups from a sample of chromospherically active stars in the RAVE catalog
Valeria Ramírez-Preciado, Carlos G. Roman-Zuñiga, Luis Aguilar +2
The purpose of this study is the identification of young ( Myr), nearby ( pc) moving groups (YNMGs) through their kinematic signature. YNMGs could be…
The APOGEE-2 Survey of the Orion Star Forming Complex II: Six-dimensional structure
Marina Kounkel, Kevin Covey, Genaro Suárez +17
We present an analysis of spectrosopic and astrometric data from APOGEE-2 and Gaia DR2 to identify structures towards the Orion Complex. By applying a hierarchical clustering algor…
