Detection of coherent low-frequency radio bursts from weak-line TTauri stars
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +7
In recent years, thanks to new facilities such as LOFAR capable of sensitive observations, much work has been done on the detection of stellar radio emission at low frequencies. Su…
Imaging Spectroscopy of CME-Associated Solar Radio Bursts
Sherry Chhabra, Dale E. Gary, Gregg Hallinan +4
We present first results of a solar radio event observed with the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) at metric wavelengths. We examine a complex event…
Detection of 24 GHz Continuum Emission from Eridani
Akshay Suresh, Shami Chatterjee, James M. Cordes +2
The nearby star has been a frequent target of radio surveys for stellar emission and extraterrestial intelligence. Using deep observations with the…
On the Correlation between L Dwarf Optical and Infrared Variability and Radio Aurorae
Tyler Richey-Yowell, Melodie M. Kao, J. Sebastian Pineda +2
Photometric variability attributed to cloud phenomena is common in L/T transition brown dwarfs. Recent studies show that such variability may also trace aurorae, suggesting that lo…
Multi-Epoch VLBI of L Dwarf Binary 2MASS J0746+2000AB: Precise Mass Measurements and Confirmation of Radio Emission from Both Components
Qicheng Zhang, Gregg Hallinan, Walter Brisken +2
Surveys have shown that up to one tenth of all ultracool dwarfs (UCDs) are appreciable radio emitters, with their emission attributed to a combination of gyrosynchrotron radiation…
Prevalence of SED turndown among classical Be stars: Are all Be stars close binaries?
Robert Klement, A. C. Carciofi, T. Rivinius +16
Rapid rotation is a fundamental characteristic of classical Be stars and a crucial property allowing for the formation of their circumstellar disks. Past evolution in a mass and an…
