Yasuo Fukui et al 2018 ApJ 859 166
New molecular data from the Orion Nebula Cluster suggest that that the two clouds collided with each other < 0.1 Myr ago, triggeing the formation of the high-mass stars observed.
David Jewitt et al 2018 AJ 155 231
New Hubble Space Telescope observations of the unique, dust-ejecting inner-belt asteroid 311P/PANSTARRS suggest that this source may actually be a close, eclipsing binary.
Kate H. R. Rubin et al 2018 ApJ 859 146
Keck Cosmic Web Imager spectroscopy of the four putative images of the lensed quasar candidate J014710+463040 verify the source as a quasar at z = 2.377, for which all four source images are very bright.
Christian R. Hayes et al 2018 ApJL 859 L8
Chemical analysis of the Triangulum-Andromeda (TriAnd) system — a low-latitude Milky Way overdensity — suggest that it’s associated with the galactic disk, and, therefore, that the disk extends out beyond 24 kpc.
Christina C. Williams et al 2018 ApJS 236 33
A model is introduced to describe the evolution of galaxy number counts, morphologies, and spectral energy distributions across a wide range of redshifts and stellar masses.
P. Heinzel and K. Shibata 2018 ApJ 859 143
Under conditions expected during superflares, the continuum brightening due to extended loop arcades can significantly contribute to stellar flux detected by Kepler on M-dwarf and solar-type superflare stars.
