Monitoring radio activity of a sample of M-dwarf stars

A growing number of planets discovered around M-dwarfs has motivated new, large surveys and studies of habitability of planets in tight, tidally locked orbits around low-mass stars. One of the related concerns is that stellar activity, especially flaring, which is common in late-type stars, may prevent planetary habitability. We propose to initiate a multifrequency monitoring of a sample of M-dwarfs that are also targets of Penn State's upcoming radial velocity survey with the near-infrared Habitable Planet Finder spectrograph. We plan to observe at L, S, and C-band frequencies and use the Mock spectrometer. As radio observations provide the most direct diagnostic of stellar flaring, our program will characterize the activity of stars with planets orbiting in their habitable zones. To design and calibrate our program, we would like to begin with a sample of five nearby dwarfs that already have extensive optical characterizations and are known to be active in this wavelength range.
