# TESS Program G022135 Title: Stellar Structure And Evolution Put To The Test With Asteroseismology Of O And B Stars PI: Pedersen, May - Katholieke Universiteit Leuven Type: SMALL Summary: Through the chemical enrichment of their environment, massive stars play an important role in many fields of modern astrophysics and largely guide the evolution of the Universe as a whole. While major shortcomings prevail in their stellar structure and evolution theory, asteroseismology provides a promising tool for calibrating their internal properties by studying stellar pulsations which probe different depths of the stellar interior. However, due to the limitations of ground based observational campaigns as well as previous space missions, tight observational constraints have only been achievable for a handful of massive stars. With this science case we aim to remedy this situation by studying 73 O and B stars observed by TESS for at least 3 sectors in the northern hemisphere. # Sector 014 targets observed (39) 229452839,294.401,64.0166,8.13,G022135 229479255,295.6465,64.0301,9.14,G022135 229966103,289.5486,60.9601,7.21,G022135 233387809,301.717,57.3732,9.36,G022135 233539736,281.0183,60.7701,10.48,G022135;G022062 233613741,283.4362,60.0179,7.15,G022135;G022169 236785664,283.0091,59.6671,6.98,G022135;G022169 236872887,302.914,63.5274,7.7,G022135;G022062 243276811,288.2375,58.1079,7.7,G022135 256662953,300.7481,65.8615,9.5,G022135 269598007,301.0067,66.0409,9.25,G022135 284563819,291.4448,58.0273,6.72,G022135 287193769,292.5378,57.2435,10.06,G022135 377099704,285.1145,56.5252,8.97,G022135 232643392,281.6143,54.277,9.69,G022135 236773991,282.5905,54.3009,7.57,G022135 341816971,267.6306,57.4436,8.01,G022135 47583864,278.5997,51.1132,7.96,G022135 48022676,281.6796,52.9879,5.95,G022135;G022169;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 158490159,287.5988,47.1622,11.23,G022135 48217508,283.1198,48.4039,10.01,G022135 48503549,285.0571,50.5335,5.58,G022135;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 278358300,307.4277,50.3186,9.08,G022135 352556540,306.3867,54.6842,7.12,G022135;G022169 198279946,250.2761,62.308,6.78,G022135;G022062 198388195,258.0954,57.2234,8.36,G022135 198456386,261.6738,59.7487,9.86,G022135 224607716,255.8917,57.4999,8.18,G022135 229793060,284.7193,69.5314,6.62,G022135;G022062 258461221,300.0167,68.4368,8.06,G022135 258954765,289.1008,67.1351,8.16,G022135 269696438,301.6071,68.291,8.72,G022135 360020620,300.3926,70.4546,7.84,G022135 376869778,283.3887,75.7875,6.79,G022135 420114700,290.6854,74.6337,8.78,G022135 159502560,246.3494,79.2647,9.64,G022135 160553438,242.7063,75.8776,5.59,G022135;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 229670516,251.5915,77.0215,10.14,G022135 233497379,249.3017,76.1638,9.8,G022135 #
