LEGUS & Ha-LEGUS obs. of NGC4449 star clusters
We present a new catalog and results for the cluster system of the starburst galaxy NGC 4449, based on multiband imaging observations taken as part of the LEGUS and... -
APOGEE-Kepler Cool Dwarf star ages determination
We use models of stellar angular momentum evolution to determine ages for ~500 stars in the APOGEE-Kepler Cool Dwarfs sample. We focus on lower-main-sequence stars, where other... -
Spitzer obs. of YSOs in the SMOG field
In this paper we undertake a study of the 21deg^2^ SMOG field, a Spitzer cryogenic mission Legacy program to map a region of the outer Milky Way toward the Perseus and outer... -
Vertical motions of APOGEE & Gaia red clump stars
It has long been known that the vertical motions of Galactic disk stars increase with stellar age, commonly interpreted as vertical heating through orbit scattering. Here we map... -
High-res. spectroscopy of LAMOST Li-rich giants
The discovery of Li-rich giants has introduced a new challenge for standard stellar evolution models. To resolve this issue, the number of this type of object has been rapidly... -
Mass accretion rates of PMS stars. VI. LH95 in LMC
We report on the accretion properties of low-mass stars in the LH 95 association within the Large Magellanic Cloud. Using noncontemporaneous wideband optical and narrowband... -
Environment and hosts of Type Ia supernovae
The reliability of Type Ia Supernovae (SNe Ia) may be limited by the imprint of their galactic origins. To investigate the connection between supernovae and their host... -
HAZMAT. V. UV and X-ray evolution of K stars
Knowing the high-energy radiation environment of a star over a planet's formation and evolutionary period is critical in determining if that planet is potentially habitable and... -
A combined Chandra & LAMOST study of stellar activity
We probed stellar X-ray activity over a wide range of stellar parameters, using Chandra and Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) data. We measured... -
Ages & masses for GPS1 WD-MS binary systems
Observational tests of stellar and Galactic chemical evolution call for the joint knowledge of a star's physical parameters, detailed element abundances, and precise age. For... -
DSHARP I. Sample, ALMA obs. log and overview
We introduce the Disk Substructures at High Angular Resolution Project (DSHARP), one of the initial large programs conducted with the Atacama Large Millimeter/submillimeter... -
A large moving group within the LCC association
Scorpius-Centaurus is the nearest OB association, and its hundreds of members are divided into subgroups, including the Lower Centaurus Crux (LCC). Here we study the dynamics of... -
Kinematic data of YNMGs from RAVE & Gaia
The purpose of this study is the identification of young (1<age<100Myr), nearby (d<=100pc) moving groups (YNMGs) through their kinematic signature. YNMGs could be the... -
Fluxes & physical param. of blended YSOs
Despite significant evidence suggesting that intermediate- and high-mass stars form in clustered environments, how stars form when the available resources are shared is still... -
Post-starburst galaxy ages from SDSS
Detailed modeling of the recent star formation histories (SFHs) of post-starburst (or "E+A") galaxies is impeded by the degeneracy between the time elapsed since the starburst... -
HST observations of nearby core-collapse SNe
We age-date the stellar populations associated with 12 historic nearby core-collapse supernovae (CCSNe) and two supernova impostors; from these ages, we infer their initial... -
Keck HIRES obs. of 245 subgiants (retired A stars)
Exoplanet surveys of evolved stars have provided increasing evidence that the formation of giant planets depends not only on stellar metallicity ([Fe/H]) but also on the mass... -
PS1 proper-motion survey for brown dwarfs. I. Taurus
We are conducting a proper-motion survey for young brown dwarfs in the Taurus-Auriga molecular cloud based on the Pan-STARRS1 3{pi} Survey. Our search uses multi-band photometry... -
Tracers of stellar mass-loss. II.
I present integrated colors and surface brightness fluctuation magnitudes in the mid-infrared (IR), derived from stellar population synthesis models that include the effects of... -
PHAT. XIX. Formation history of M31 disk
We map the star formation history across M31 by fitting stellar evolution models to color-magnitude diagrams of each 83"x83" (0.3x1.4kpc, deprojected) region of the Panchromatic...
