A low-mass companion desert among intermediate-mass visual binaries: The scaled-up counterpart to the brown dwarf desert
G. Duchene, J. T. Oon, R. J. De Rosa +8
We present a high-contrast imaging survey of intermediate-mass (1.75--4.5 ) stars to search for the most extreme stellar binaries, i.e., for the lowest mass stellar compan…
Characterisation of the NUV and Optical Emission and Temperature of Flares from Ross 733 with Swift and TESS
James A. G. Jackman
We present the results of a coordinated campaign to simultaneously observe the M star binary Ross 733 simultaneously in the optical and near-ultraviolet (NUV) with TESS and Swift r…
Extending Optical Flare Models to the UV: Results from Comparing of TESS and GALEX Flare Observations For M Dwarfs
James A. G. Jackman, Evgenya Shkolnik, Chase Million +3
The ultraviolet (UV) emission of stellar flares may have a pivotal role in the habitability of rocky exoplanets around low-mass stars. Previous studies have used white-light observ…
The Mouse that Squeaked: A small flare from Proxima Cen observed in the millimeter, optical, and soft X-ray with Chandra and ALMA
Ward S. Howard, Meredith A. MacGregor, Rachel Osten +10
We present millimeter, optical, and soft X-ray observations of a stellar flare with an energy squarely in the regime of typical X1 solar flares. The flare was observed from Proxima…
Infrared spectroscopy of the 2019 eruption of the recurrent nova V3890 Sgr: separation into equatorial and polar winds revealed
A. Evans, T. R. Geballe, C. E. Woodward +4
We present infrared spectroscopy of the 2019 eruption of the recurrent nova V3890 Sgr, obtained over the period 5.1-46.3 days after the eruption. The spectrum of the red giant beca…
Modules for Experiments in Stellar Astrophysics (MESA): Time-Dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure
Adam S. Jermyn, Evan B. Bauer, Josiah Schwab +19
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic different…
