# TESS Program G022169 Title: Photometric Analysis Of Be Stars' Outbursts In The Northern Ecliptic Hemisphere PI: Emilio, Marcelo - Universidade Estadual De Ponta Grossa Type: SMALL Summary: We propose the characterization of outbursts in northern Be stars. Classical Be stars are rapid rotators of spectral type B and luminosity class V-III which have an equatorially concentrated circumstellar disk. The disk is fed by discrete mass loss events called outbursts. Rapid rotation alone cannot explain the ejection episodes, and non-radial pulsations (NRP) have been proposed as an explanation. We propose 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 2-min cadence observations. Fourier analysis of photometric data will be performed using a methodology developed by our group for CoRoT and K2 Be stars. # Sector 014 targets observed (6) 173066803,299.98,37.0429,5.36,G022169;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 42360166,302.3568,36.8397,5.22,G022169;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 233613741,283.4362,60.0179,7.15,G022135;G022169 236785664,283.0091,59.6671,6.98,G022135;G022169 48022676,281.6796,52.9879,5.95,G022135;G022169;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 352556540,306.3867,54.6842,7.12,G022135;G022169 #
