Title: Exploring Outbursts In Be Stars With TESS And Ground-Based Spectroscopy

PI: Emilio, Marcelo - Universidade Estadual De Ponta Grossa

Type: MINI

Summary: We propose to continue the search for and characterization of discrete mass-loss events (outbursts) in Be stars located in TESS observation fields as well as in those observed during the Kepler/K2 mission. Rapid rotation alone cannot explain the ejection episodes of Be stars, and non-radial pulsations (NRP) have been proposed as an explanation. Our goal is to verify the correlation between the NRP regime and the feeding of the envelope by combining ground-based spectroscopy data with the identification of outbursts and the measurement of small changes in pulsation frequencies with TESS 20-second cadence observations. Fourier analysis of photometric data is performed using a methodology developed for CoRoT and K2 Be stars.
