Optically Quiet, But FUV Loud: Results from comparing the far-ultraviolet predictions of flare models with TESS and HST

James A. G. Jackman, Evgenya L. Shkolnik, R. O. Parke Loyd +1

The far-ultraviolet (FUV) flare activity of low-mass stars has become a focus in our understanding of the exoplanet atmospheres and how they evolve. However, direct detection of FU…

A Dragon's Flame of Many Colours: Multi-wavelength Observations of Flares from the Active M Binary CR Draconis

James A. G. Jackman, Evgenya L. Shkolnik, R. O. Parke Loyd +9

We present the results of a multi-wavelength Pro-Am campaign to study the behaviour of flares from the active M1.5V star binary CR Draconis. CR Dra was observed with TESS 20-s phot…

Statistical Signatures of Nanoflare Activity. III. Evidence of Enhanced Nanoflaring Rates in Fully Convective stars as Observed by the NGTS

S. D. T. Grant, D. B. Jess, C. J. Dillon +11

Previous examinations of fully-convective M-dwarf stars have highlighted enhanced rates of nanoflare activity on these distant stellar sources. However, the specific role the conve…

HAZMAT. IX. An Analysis of the UV and X-Ray Evolution of Low-Mass Stars in the Era of Gaia

Tyler Richey-Yowell, Evgenya L. Shkolnik, Adam C. Schneider +6

Low mass stars ( M) are some of the best candidates for hosting planets with detectable life because of these stars' long lifetimes and relative planet to star ma…

Combined Spectroscopic and Photometric Analysis of Flares in the Dwarf M Star EV Lacertae

David Boyd, Robert Buchheim, Sean Curry +6

We report results of an observing campaign to study the dwarf M flare star EV Lacertae. Between October 2021 and January 2022 we obtained concurrent B band photometry and low resol…

Flares, Rotation, Activity Cycles and a Magnetic Star-Planet Interaction Hypothesis for the Far Ultraviolet Emission of GJ 436

R. O. Parke Loyd, P. C. Schneider, James A. G. Jackman +6

Variability in the far ultraviolet (FUV) emission produced by stellar activity affects photochemistry and heating in orbiting planetary atmospheres. We present a comprehensive anal…
