Hipparcos, Gaia, and RVs reveal that the radio emitting F star HD 220242 has an M dwarf companion, a likely source of the radio emission
Megan Delamer, Guðmundur Stefánsson, Suvrath Mahadevan +18
The detection of circularly polarized, low frequency radio emission offers the tantalizing possibility of the observation of interactions between stars and their possible substella…
The First Estimation of the Ambipolar Diffusivity Coefficient from Multi-Scale Observations of the Class 0/I Protostar, HOPS-370
Travis J. Thieme, Shih-Ping Lai, Yueh-Ning Lee +2
Protostars are born in magnetized environments. As a consequence, the formation of protostellar disks can be suppressed by the magnetic field efficiently removing angular momentum…
The search for failed supernovae with the Large BinocularTelescope: The Mid-IR Counterpart to N6946-BH1
C. S. Kochanek, J. M. M. Neustadt, K. Z. Stanek
We present JWST MIRI 5.6, 10 and 21 micron observations of the candidate failed supernova N6946-BH1 along with HST WFPC/IR 1.1 and 1.6 micron data and ongoing optical monitoring da…
Transients Obscured by Dusty Disks
C. S. Kochanek
Dust absorption is invoked in a number of contexts for hiding a star that has survived some sort of transient event from view. Dust formed in a transient is expanding away from the…
Ultrafaint Dwarf Galaxy Candidates in the M81 Group: Signatures of Group Accretion
Eric F. Bell, Adam Smercina, Paul A. Price +8
The faint and ultrafaint dwarf galaxies in the Local Group form the observational bedrock upon which our understanding of small-scale cosmology rests. In order to understand whethe…
A Search for Unbound Stellar Companions to Pulsar J1124-5916
C. S. Kochanek
We searched for and found no higher mass (>3Msun) unbound binary stellar companions to the progenitor of pulsar J1124-5916. There are lower mass candidates, but they all have high…
A Non-Detection of Red Supergiant Convection in Gaia
C. S. Kochanek
Large scale surface convection on red supergiants (RSGs) can lead to shifts in the photocenter of the star which might be measured by Gaia and used as a new probe of the surface dy…
Stellar Binaries That Survive Supernovae
C. S. Kochanek, K. Auchettl, C. Belczynski
The number of binaries containing black holes or neutron stars depends critically on the fraction of binaries that survive supernova explosions. We searched for surviving star plus…
ROBO: a Model and a Code for the Study of the Interstellar Medium
T. Grassi, P. Krstic, E. Merlin +3
We present ROBO, a model and its companion code for the study of the interstellar medium (ISM). The aim is to provide an accurate description of the physical evolution of the ISM a…
