A Long-duration Superflare on the K Giant HD 251108

A Long-duration Superflare on the K Giant HD 251108

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 limits on the magnetic field strength and thus constrain the mechanism of the underlying dynamo. HD 251108 is a Li-rich...
