TL;DR: A luminous ultraviolet–optical flare from the nuclear region of an inactive galaxy at a redshift of 0.1696 is reported and it is determined that the disrupted star was a helium-rich stellar core, modulo a factor dependent on the mass and radius of the star disrupted.
Journal ArticleDOI
First GLIMPSE Results on the Stellar Structure of the Galaxy
Robert A. Benjamin,Ed Churchwell,Brian Babler,Remy Indebetouw,Marilyn R. Meade,Barbara A. Whitney,Christer Watson,Mark G. Wolfire,Michael J. Wolff,Richard Ignace,T. M. Bania,S. Bracker,Dan P. Clemens,Laura Chomiuk,Milton Cohen,John M. Dickey,James M. Jackson,Henry A. Kobulnicky,E. P. Mercer,John S. Mathis,Susan R. Stolovy,B. Uzpen +21 more
TL;DR: The GLIMPSE point source catalog of mid-infrared sources toward the inner Galaxy, 10° ≤ |l| ≤ 65° and |b| ≤ 1°, was used to determine the distribution of stars in Galactic longitude, l, latitude, b, and apparent magnitude, m as mentioned in this paper.
Journal ArticleDOI
Toward a unification of star formation rate determinations in the milky way and other galaxies
TL;DR: The star formation rate (SFR) of the Milky Way remains poorly known, with often-quoted values ranging from 1 to 10 Myr −1. This situation persists despite the potential for the Milky way to serve as the ultimate SFR calibrator for external galaxies as mentioned in this paper.
Journal ArticleDOI
On the source of the dust extinction in type Ia supernovae and the discovery of anomalously strong Na i absorption

TL;DR: In this article, high-dispersion observations of the Na I D λλ5890, 5896 and K I 7665, 7699 interstellar lines and the diffuse interstellar band at 5780 A in the spectra of 32 Type Ia supernovae are used as an independent means of probing dust extinction.
Journal ArticleDOI
Two stellar-mass black holes in the globular cluster M22
Jay Strader,Laura Chomiuk,Laura Chomiuk,Laura Chomiuk,Thomas J. Maccarone,James Miller-Jones,Anil C. Seth +6 more
TL;DR: The identification of two black holes in one cluster shows that ejection of black holes is not as efficient as predicted by most models, and it is argued that M22 may contain a total population of ∼5–100 black holes, which could arise from heating produced by the black holes.
