A Survey of Deuterated Ammonia in the Cepheus Star-Forming Region L1251
Maria Galloway-Sprietsma, Yancy L. Shirley, James Di Francesco +4
Understanding the chemical processes during starless core and prestellar core evolution is an important step in understanding the initial stages of star and disk formation. This pr…
Heartbeat Stars: Spectroscopic Orbital Solutions for Six Eccentric Binary Systems
Rachel A. Smullen, Henry A. Kobulnicky
We present multi-epoch spectroscopy of "heartbeat stars," eccentric binaries with dynamic tidal distortions and tidally induced pulsations originally discovered with the Kepler sat…
Toward Complete Statistics of Massive Binary Stars: Penultimate Results from the Cygnus OB2 Radial Velocity Survey
Henry A. Kobulnicky, Daniel C. Kiminki, Michael J. Lundquist +12
We analyze orbital solutions for 48 massive multiple-star systems in the Cygnus OB2 Association, 23 of which are newly presented here, to find that the observed distribution of orb…
A Fresh Catch of Massive Binaries in the Cygnus OB2 Association
Henry A. Kobulnicky, Rachel A. Smullen, Daniel C. Kiminki +6
Massive binary stars may constitute a substantial fraction of progenitors to supernovae and gamma-ray bursts, and the distribution of their orbital characteristics holds clues to t…
