Broadband 12-26 GHz Radio Radiation Reveals Evidence for Micro-flares on AU Mic

Isaiah I. Tristan, Rachel A. Osten, Yuta Notsu +2

We present sequential 12-18 and 18-26 GHz radio-band (, ) VLA observations of the 22 Myr dM1e star AU Mic. We detect two flares and two marginal events over a total of 3 con…

ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution

Allison Youngblood, Kevin France, Brian Fleming +37

The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…

A 7 Day Multiwavelength Flare Campaign on AU Mic. IV: Quiescent Gyrosynchrotron and Gyroresonance Radiation from 12 to 25 GHz

Isaiah I. Tristan, Rachel A. Osten, Yuta Notsu +2

We present an analysis of the radio quiescent data from a multiwavelength campaign of the active M-dwarf flare star AU Mic (dM1e) that occurred in October 2018. Using Ku-band data…

Radio and Optical Flares on the dMe Flare Star EV Lac

Rachel A. Osten, Adam F. Kowalski, Suzanne Hawley +4

We present the results of a coordinated campaign to observe radio and optical stellar flares from the nearby M dwarf flare star EV~Lac. From a total of 27 hours of radio and 29 hou…

A Seven-Day Multi-Wavelength Flare Campaign on AU Mic III: Quiescent and Flaring Properties of the X-ray Spectra and Chromospheric lines

Yuta Notsu, Isaiah I. Tristan, Rachel A. Osten +3

We present the X-ray quiescent and flaring properties from a unique, 7-day multiwavelength observing campaign on the M1 flare star AU Mic. Combining the XMM-Newton X-ray spectra wi…

A 7-Day Multi-Wavelength Flare Campaign on AU Mic. II: Electron Densities and Kinetic Energies from High-Frequency Radio Flares

Isaiah I. Tristan, Rachel A. Osten, Yuta Notsu +6

M dwarfs are the most common type of star in the solar neighborhood, and many exhibit frequent and highly energetic flares. To better understand these events across the electromagn…
