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…
Machine Learning Classification of Kuiper Belt Populations
Rachel A. Smullen, Kathryn Volk
In the outer solar system, the Kuiper Belt contains dynamical sub-populations sculpted by a combination of planet formation and migration and gravitational perturbations from the p…
The highly variable time evolution of star-forming cores identified with dendrograms
Rachel A. Smullen, Kaitlin M. Kratter, Stella S. R. Offner +2
We investigate the time evolution of dense cores identified in molecular cloud simulations using dendrograms, which are a common tool to identify hierarchical structure in simulati…
The Formation and Evolution of Wide-Orbit Stellar Multiples In Magnetized Clouds
Aaron T. Lee, Stella S. R. Offner, Kaitlin M. Kratter +2
Stars rarely form in isolation. Nearly half of the stars in the Milky Way have a companion, and this fraction increases in star-forming regions. However, why some dense cores and f…
The Fate of Debris in the Pluto-Charon System
Rachel A. Smullen, Kaitlin M. Kratter
The Pluto-Charon system has come into sharper focus following the fly by of New Horizons. We use N-body simulations to probe the unique dynamical history of this binary dwarf plane…
Planet Scattering Around Binaries: Ejections, Not Collisions
Rachel A. Smullen, Kaitlin M. Kratter, Andrew Shannon
Transiting circumbinary planets discovered by Kepler provide unique insight into binary star and planet formation. Several features of this new found population, for example the ap…
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…
