Time-lapse Very Long Baseline Interferometry Imaging of the Close Active Binary HR 1099
Walter W. Golay, Robert L. Mutel, Evan E. Abbuhl
We report multiepoch astrometric very long baseline interferometry observations of the chromospherically active binary HR 1099 (V711 Tau, HD 22468) at six epochs over 63 days using…
A search for thermal gyro-synchrotron emission from hot stellar coronae
Walter W. Golay, Robert L. Mutel, Dani Lipman +1
We searched for thermal gyro-synchrotron radio emission from a sample of five radio-loud stars whose X-ray coronae contain a hot ( K) thermal component. We used the JVLA…
Eclipse Timing Modeling of Three Post-Common Envelope Binaries: Hybrid Solutions
Xinyu Mai, Robert L. Mutel
We report 90 new observations of three post common envelope binaries at primary eclipse spanning between December 2018 to February 2022. We combine recent primary eclipse timing ob…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
Meter- to Millimeter Emission from Cool Stellar Systems: Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade
Jan Forbrich, Peter K. G. Williams, Emily Drabek-Maunder +12
Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA,…
First Resolution of Microlensed Images
Subo Dong, A. Mérand, F. Delplancke-Ströbele +12
We employ VLTI GRAVITY to resolve, for the first time, the two images generated by a gravitational microlens. The measurements of the image separation θ_{-,+}=3.78 +/- 0.05 mas, an…
