The Proxima Centauri Campaign -- First Constraints On Millimeter Flare Rates from ALMA
Kiana Burton, Meredith A. MacGregor, Rachel A. Osten +6
Proxima Centauri (Cen) has been the subject of many flaring studies due to its proximity and potential to host habitable planets. The discovery of millimeter flares from this M dwa…
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…
Discovery of an Extremely Short Duration Flare from Proxima Centauri Using Millimeter through FUV Observations
Meredith A. MacGregor, Alycia J. Weinberger, R. O. Parke Loyd +17
We present the discovery of an extreme flaring event from Proxima Cen by ASKAP, ALMA, HST, TESS, and the du Pont Telescope that occurred on 2019 May 1. In the millimeter and FUV, t…
A Flare-Type IV Burst Event from Proxima Centauri and Implications for Space Weather
Andrew Zic, Tara Murphy, Christene Lynch +10
Studies of solar radio bursts play an important role in understanding the dynamics and acceleration processes behind solar space weather events, and the influence of solar magnetic…
Properties of M Dwarf Flares at Millimeter Wavelengths
Meredith A. MacGregor, Rachel A. Osten, A. Meredith Hughes
We report on two millimeter flares detected by ALMA at 220 GHz from AU Mic, a nearby M dwarf. The larger flare had a duration of only sec, with peak …
Constraints on Planetesimal Collision Models in Debris Disks
Meredith A. MacGregor, David J. Wilner, Claire Chandler +6
Observations of debris disks offer a window into the physical and dynamical properties of planetesimals in extrasolar systems through the size distribution of dust grains. In parti…
