PublicationThe evolution of a supernova remnant in a strongly magnetized interstellar medium
Several aspects of the evolution of an SNR into a low-beta ISM are investigated. The presence of a strong magnetic field in the unperturbed ISM is found to have...

PublicationThe Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS
Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones...
