# TESS Program G08088 Title: Periodic Varibility In Erosita-Discovered Accreting Compact White-Dwarf Binaries PI: Schwope, Axel - Leibniz-Institut Fur Astrophysik Potsdam (Aip) Type: MINI Summary: Accreting compact white-dwarf binaries (ACWDBs) are crucial to understand several important astrophysical phenomena such as Type Ia supernovae and gravitational waves. Despite their fundamental importance for astrophysics and recent progress with the comprehension of these objects, we still do not fully understand how they form and evolve. Progress is hampered by the presently available samples that are either too small or heavily biased through various detection routes. All ACWDBs are known to be X-ray emitters which allows to build large samples of CVs from the stack of eROSITA all-sky surveys and associated Gaia sources. Here we propose photometric follow-up with TESS of spectroscopically confirmed systems for classifications and period determination. # Sector 097 targets observed (2 min: 47, 20 s: 7) 160196160,27.5507,-45.3554,17.99,G08088 631854368,35.8265,-43.2839,19.55,G08088 631964972,29.5136,-38.1561,19.18,G08088 632002275,36.499,-35.7553,19.84,G08088 651147139,50.9012,-35.402,18.87,G08088 651223313,43.201,-39.9866,18.79,G08088;20SECONDTARGET 651319301,51.6905,-34.4403,20.34,G08088;G08036 632462806,25.6056,-22.2669,18.07,G08088;G08036 144103667,59.1938,-44.8055,16.08,G08088 650951924,58.4273,-46.4081,19.66,G08088;G08036 651005355,53.336,-44.8617,17.66,G08088;20SECONDTARGET 651065485,47.4173,-39.9475,20.2,G08088 651102603,55.6205,-38.8276,20.4,G08088 631743126,33.436,-51.282,19.65,G08088 631801463,27.9662,-47.641,18.51,G08088 650854785,43.8886,-47.8452,16.12,G08088;G08036;G08079 220519449,41.8371,-60.8474,18.16,G08088;20SECONDTARGET 685000540,60.1597,-61.8837,18.98,G08088;G08002;G08062 685432238,70.1814,-49.4204,19.1,G08088 685498751,65.194,-46.9394,19.66,G08088 220438568,73.9441,-57.1264,18.37,G08088 350297825,83.7106,-58.028,14.13,G08088;G08108;G08158;20SECONDTARGET 350765919,89.3022,-59.5904,14.18,G08088;G08036;G08108 381975895,77.0848,-54.8162,17.83,G08088 382256692,82.3691,-58.9128,14.14,G08088;G08036;G08108 685158436,76.2809,-58.4398,20.59,G08088 685239653,70.9532,-59.8184,17.97,G08088;G08036 734581283,83.8958,-53.8091,19.46,G08088 737357865,91.5114,-60.6615,20.08,G08088 140597969,68.7905,-75.4621,16.52,G08088 25133286,62.2986,-71.2948,13.58,G08088;20SECONDTARGET 277101110,83.9208,-66.8649,15.27,G08088 358154354,70.4199,-76.6126,16.48,G08088;G08036;G08158 38634085,65.1657,-62.7502,16.86,G08088;G08036 679861309,66.9569,-67.0764,17.22,G08088;20SECONDTARGET 684931651,63.6205,-63.3294,18.88,G08088 272551828,121.865,-76.5333,15.45,G08088 293271581,98.9003,-62.6401,12.47,G08088;G08036;G08108 339772356,111.3838,-58.0569,15.91,G08088;G08036;G08108 349408306,110.4262,-64.0141,15.85,G08088;G08036;G08108;20SECONDTARGET 349477778,110.6422,-62.996,15.43,G08088;G08108 349572491,111.7662,-63.3312,14.82,G08088;G08036;G08108;G08158 349682410,112.6555,-61.8958,14.56,G08088;G08036;G08108 737278103,99.8666,-62.397,19.74,G08088 737436327,97.2233,-57.3473,17.45,G08088;G08036 737490894,98.1154,-56.648,19.25,G08088 765310516,109.9833,-64.9692,19.39,G08088 #
