A magnetic field study of two fast-rotating, radio bright M dwarfs. StKM 1-1262 and V374 Peg

S. Bellotti, P. I. Cristofari, J. R. Callingham +8

Radio observations at low frequencies are sensitive to the magnetic activity of stars and the plasma environment surrounding them. The accurate interpretation of the processes unde…

Constraining the Mass Loss and the Kinetic Energy of Solar Coronal Mass Ejections with Far-Ultraviolet Flares

Nuri Park, Evgenya L. Shkolnik, Joe Llama

Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres. For instance, strong…

Building SPARCS, an Ultraviolet Science CubeSat for Exoplanet Habitability Studies, Technology Advancements, and Mission Training

Evgenya L. Shkolnik, David R. Ardila, Logan Jensen +17

The Star-Planet Activity Research CubeSat (SPARCS) is a NASA-funded 6U-CubeSat mission designed to monitor ultraviolet (UV) radiation from low-mass stars. These stars' relatively h…

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…

The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID

Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37

We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…

Refining the Stellar Parameters of Ceti: a Pole-on Solar Analog

Maria Korolik, Rachael M. Roettenbacher, Debra A. Fischer +16

To accurately characterize the planets a star may be hosting, stellar parameters must first be well-determined. Ceti is a nearby solar analog and often a target for exoplanet s…
