# TESS Program G011203 Title: Searching For The Remnants Of Disrupted Planetary Systems Around White Dwarfs PI: Braker, Ian - University Of Leicester Type: N/A Summary: The evolution of planetary systems after the main sequence is largely unknown and no planets around isolated White Dwarfs (WD) have yet been detected. Some show evidence of metal pollution or gas and dust discs indicating that planetesimals and even dwarf planets up to the size of Pluto strayed too close to the WD and have subsequently been tidally disrupted. However there is only one known system where this can be actively observed, WD1145+017. Such objects would only survive a star's evolution to a WD at distances greater than at least 1AU, implying these objects may have been scattered by unseen planets. We propose to observe all WDs with magnitudes <16 with similar evidence of planetary systems to search for further examples of ongoing tidal disruption of planetesimals. # Sector 001 targets observed (21) 115075496,316.1956,-36.257,15.57,G011203 126910998,317.9055,-42.9701,14.11,G011113;G011203 382315106,324.1628,-36.4003,16.24,G011203 204543760,327.2271,-35.5806,16.3,G011203;G011288 80083663,331.1449,-30.0186,13.82,G011113;G011203 290165383,319.7691,-25.9703,15.66,G011203 302333352,320.4374,-27.0367,13.26,G011113;G011203 394015496,329.5996,-58.8982,13.86,G011113;G011203 394521800,334.9538,-65.4915,14.56,G011113;G011294;G011203 161458992,346.1297,-48.6828,14.93,G011203 231668155,319.9062,-55.8383,14.24,G011113;G011203 370239521,327.6009,-53.9769,13.52,G011113;G011203 271503343,7.7274,-63.3623,14.69,G011113;G011203 394632742,351.4338,-67.3788,16.77,G011203 261646823,19.3563,-82.3003,15.1,G011203 263076776,17.0807,-80.5235,13.02,G011113;G011203 350155155,53.0673,-83.6383,17.83,G011203 220576880,47.8433,-62.2541,16.2,G011113;G011294;G011203 232065830,26.5514,-70.3388,15.26,G011113;G011203 262921847,53.6435,-64.0161,13.29,G011203;G011281 33840009,64.9072,-73.0623,14.92,G011113;G011203 #
