Discovery and Characterization of 3000+ Main-Sequence Binaries from APOGEE Spectra
Kareem El-Badry, Yuan-Sen Ting, Hans-Walter Rix +7
We develop a data-driven spectral model for identifying and characterizing spatially unresolved multiple-star systems and apply it to APOGEE DR13 spectra of main-sequence stars. Bi…
The Impact of Star Formation Histories on Stellar Mass Estimation: Implications from the Local Group Dwarf Galaxies
Hong-Xin Zhang, Thomas H. Puzia, Daniel R. Weisz
Local Group (LG) galaxies have relatively accurate SFHs and metallicity evolution derived from resolved CMD modeling, and thus offer a unique opportunity to explore the efficacy of…
The ISLAnds Project III: Variable Stars in Six Andromeda Dwarf Spheroidal Galaxies
Clara E. Martínez-Vázquez, Matteo Monelli, Edouard J. Bernard +15
We present a census of variable stars in six M31 dwarf spheroidal satellites observed with the Hubble Space Telescope. We detect 870 RR Lyrae (RRL) stars in the fields of And I (29…
Signatures of unresolved binaries in stellar spectra: implications for spectral fitting
Kareem El-Badry, Hans-Walter Rix, Yuan-Sen Ting +5
The observable spectrum of an unresolved binary star system is a superposition of two single-star spectra. Even without a detectable velocity offset between the two stellar compone…
The Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE): The Dust Extinction Curve from Red Clump Stars
Petia Yanchulova Merica-Jones, Karin M. Sandstrom, L. Clifton Johnson +6
We use Hubble Space Telescope (HST) observations of red clump stars taken as part of the Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE) program to measure…
Panchromatic Hubble Andromeda Treasury. XIX. The Ancient Star Formation History of the M31 Disk
Benjamin F. Williams, Andrew E. Dolphin, Julianne J. Dalcanton +7
We map the star formation history across M31 by fitting stellar evolution models to color-magnitude diagrams of each 8383 (0.31.4 kpc, deprojected) region o…
