# TESS Program G04079 Title: Asteroseismology Of Hot White Dwarf Stars And Planetary Nebula Nuclei PI: Kawaler, Steven - Iowa State University Type: SMALL Summary: This program will obtain short cadence data on known pulsating hot white dwarf (GW Vir) stars and pulsating planetary nebula nuclei (PNNVs). The science goal is to explore the coherence of the known oscillations. K2 data showed that some longer-period modes in GW Vir itself showed evidence of unexpected stochastic behavior, similar to that seen in long-period modes in cooler white dwarfs. We plan to study this effect in known hot pulsators to test connections between pulsation and convection. The high duty cycle and long duration of TESS data, which far exceed what is available from ground-based studies, are needed. While 2 minute integrations will suffice for all targets, those with short periods can benefit from 20 second integrations to eliminate aliases. # Sector 040 targets observed (2 min: 2, 20 s: 0) 233689607,275.4671,64.3648,15.47,G04079 1102584065,229.1932,73.8687,17.12,G04200;G04079;G04177 # Sector 041 targets observed (2 min: 1, 20 s: 0) 1102475240,225.54,66.2054,16.86,G04137;G04079;G04177 # Sector 042 targets observed (2 min: 2, 20 s: 0) 610818756,4.2143,-1.2249,17.19,G04079 471015192,21.3438,20.2991,16.1,G04079;G04177 # Sector 043 targets observed (2 min: 1, 20 s: 0) 471015192,21.3438,20.2991,16.1,G04079;G04177 # Sector 044 targets observed (2 min: 4, 20 s: 1) 247056967,112.2613,13.2468,16.41,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET 60947424,112.2949,20.9118,10.91,G04079 446005482,111.3945,29.4906,15.19,G04079 331986754,131.7227,17.8795,14.55,G04079 # Sector 045 targets observed (2 min: 5, 20 s: 1) 446005482,111.3945,29.4906,15.19,G04079 247056967,112.2613,13.2468,16.41,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET 60947424,112.2949,20.9118,10.91,G04079 331986754,131.7227,17.8795,14.55,G04079 903572339,163.251,17.8258,17.28,G04079;G04177 # Sector 046 targets observed (2 min: 8, 20 s: 3) 331986754,131.7227,17.8795,14.55,G04079 446005482,111.3945,29.4906,15.19,G04079 247056967,112.2613,13.2468,16.41,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET 60947424,112.2949,20.9118,10.91,G04079 903572339,163.251,17.8258,17.28,G04079;G04177 325253096,176.6467,0.2093,15.64,G04079 35062562,180.4415,-3.7613,15.2,G04137;G04079;G04177;20SECONDTARGET 421193120,178.5628,-3.2014,16.6,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET # Sector 047 targets observed (2 min: 5, 20 s: 0) 446005482,111.3945,29.4906,15.19,G04079 741726060,119.4651,53.4214,17.58,G04079;G04177 743318051,107.3853,61.8053,17.41,G04137;G04079;G04177 1102584065,229.1932,73.8687,17.12,G04200;G04079;G04177 233689607,275.4671,64.3648,15.47,G04079 # Sector 048 targets observed (2 min: 2, 20 s: 0) 1102475240,225.54,66.2054,16.86,G04137;G04079;G04177 1102584065,229.1932,73.8687,17.12,G04200;G04079;G04177 # Sector 049 targets observed (2 min: 5, 20 s: 1) 1001265917,216.4811,53.2571,16.4,G04079;G04177 193990614,230.444,52.3678,16.06,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET 1102475240,225.54,66.2054,16.86,G04137;G04079;G04177 1102584065,229.1932,73.8687,17.12,G04200;G04079;G04177 233689607,275.4671,64.3648,15.47,G04079 # Sector 050 targets observed (2 min: 3, 20 s: 0) 1001265917,216.4811,53.2571,16.4,G04079;G04177 1102475240,225.54,66.2054,16.86,G04137;G04079;G04177 233689607,275.4671,64.3648,15.47,G04079 # Sector 051 targets observed (2 min: 2, 20 s: 1) 1270717309,257.1986,42.6836,17.15,G04200;G04079;G04177 193990614,230.444,52.3678,16.06,G04200;G04137;G04079;G04036;G04177;20SECONDTARGET # Sector 052 targets observed (2 min: 2, 20 s: 0) 1270717309,257.1986,42.6836,17.15,G04200;G04079;G04177 233689607,275.4671,64.3648,15.47,G04079 # Sector 053 targets observed (2 min: 3, 20 s: 0) 1270717309,257.1986,42.6836,17.15,G04200;G04079;G04177 233689607,275.4671,64.3648,15.47,G04079 1102584065,229.1932,73.8687,17.12,G04200;G04079;G04177 # Sector 054 targets observed (2 min: 3, 20 s: 0) 1984811130,300.1634,1.728,18.16,G04079 402913811,305.5958,20.1045,14.77,G04079 233689607,275.4671,64.3648,15.47,G04079 # Sector 055 targets observed (2 min: 6, 20 s: 2) 305150369,323.5342,6.8493,16.4,G04200;G04079;G04036;20SECONDTARGET 387371712,324.2207,12.7886,13.89,G04079 117070953,319.2845,34.2077,13.5,G04079;20SECONDTARGET 291153543,312.5086,13.5582,16.46,G04079 402913811,305.5958,20.1045,14.77,G04079 233689607,275.4671,64.3648,15.47,G04079
