Event Details & Abstracts

Abstract: Space weather involves studying both the radiation from events like flares as well as the particles accelerated in the form of stellar energetic particle (SEP) events and coronal mass ejections (CMEs). Each of these components is important for understanding the atmospheric retention and chemistry of planets as well as for characterizing habitability, although constraining stellar particle environments is notoriously challenging. A part of understanding stellar space weather requires dedicated monitoring of individual stars across a variety of wavelengths to guarantee observing both a flare and the related particle acceleration. However, coordinating long-term, simultaneous, multi-wavelength observations is difficult. To address this problem, I present the start of a pan-chromatic system dedicated to nightly monitoring of a sample of solar-type stars in order to detect flares and associated SEP and CME signatures. This system currently includes Flarescope operating at 400-550nm to look for flares and the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) operating at 13-86MHz to look for radio signatures of CMEs and SEPs. The motivation for this work is supplemented by my work identifying radio emission in the VLA Sky Survey associated with super-flaring stars.
