The Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227b

Attila Varga, Joel H. Kastner, Alexander S. Binks +2

The mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascert…

A long-duration superflare on the K giant HD 251108

Hans Moritz Günther, Dheeraj Pasham, Alexander Binks +10

Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set…
