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…

Young M dwarfs flare activity model: Towards better exoplanetary atmospheric characterisation

E. Mamonova, A. F. Kowalski, K. Herbst +2

Context. Stellar flares can significantly influence the atmospheres and habitability of orbiting exoplanets, especially around young and active M dwarfs. Understanding the temporal…

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…

Discovery of multi-temperature coronal mass ejection signatures from a young solar analogue

Kosuke Namekata, Kevin France, Jongchul Chae +14

Coronal mass ejections (CMEs) on the early Sun may have profoundly influenced the planetary atmospheres of early Solar System planets. Flaring young solar analogues serve as excell…

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…

Unveiling Unprecedented Fine Structure in Coronal Flare Loops with the DKIST

Cole A. Tamburri, Maria D. Kazachenko, Gianna Cauzzi +8

We present the highest-resolution H observations of a solar flare to date, collected during the decay phase of an X1.3-class flare on 8 August 2024 at 20:12 UT. Observations wit…

Flare frequency in M dwarfs belonging to Young Moving Groups

E. Mamonova, Y. Shan, A. F. Kowalski +1

Context. M stars are preferred targets for studying terrestrial exoplanets, for which we hope to obtain their atmosphere spectra in the next decade. However, M dwarfs have long bee…

Far-Ultraviolet Emission Line Investigation of Flares on AU Mic

Adalyn Gibson, Adam F. Kowalski, Adina D. Feinstein

The role of non-thermal proton energy transportation during solar and stellar flares is largely unknown; a better understanding of this physical process will allow us to rectify lo…

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…
