# TESS Program G05061 Title: An Acid Test Of Two Stellar Age Dating Methods PI: Melis, Carl - University Of California (San Diego) Type: MINI Summary: We propose an acid test of two "gold standard" methods for deriving ages of main sequence stars with ages greater than roughly 1 Gyr. We will obtain TESS 20 second cadence observations of old stars in wide-separation binary systems with a white dwarf, derive ages for the star from asteroseismology, then compare to ages independently estimated for the white dwarf companion. This will serve as a validation and cross-check for the usage of both methods as accurate chronometers and pave the way for making age estimates for as many single nearby old stars as possible. # Sector 056 targets observed (2 min: 2, 20 s: 2) 245367276,346.6348,19.9109,5.93,G05061;G05144;G05155;G05071;20SECONDTARGET 329759640,332.9559,56.8402,4.76,G05061;G05155;G05131;G05071;20SECONDTARGET # Sector 057 targets observed (2 min: 2, 20 s: 2) 283545765,13.2479,39.0444,7.23,G05061;G05144;20SECONDTARGET 329759640,332.9559,56.8402,4.76,G05061;G05155;G05131;G05071;20SECONDTARGET # Sector 058 targets observed (2 min: 1, 20 s: 1) 241098773,29.6397,49.2046,4.82,G05061;G05071;20SECONDTARGET # Sector 062 targets observed (2 min: 1, 20 s: 1) 198079199,64.1203,-59.3032,3.53,G05061;G05155;20SECONDTARGET # Sector 063 targets observed (2 min: 3, 20 s: 3) 40535161,174.6674,-13.2011,4.99,G05061;G05155;20SECONDTARGET 57611256,173.6177,-32.826,5.22,G05061;G05144;G05071;G05109;20SECONDTARGET 198079199,64.1203,-59.3032,3.53,G05061;G05155;20SECONDTARGET # Sector 064 targets observed (2 min: 2, 20 s: 2) 72814920,188.6759,-44.6744,5.17,G05061;G05071;G05131;20SECONDTARGET 198079199,64.1203,-59.3032,3.53,G05061;G05155;20SECONDTARGET # Sector 065 targets observed (2 min: 2, 20 s: 2) 179348425,236.8678,-37.9177,5.37,G05061;G05155;G05144;G05071;G05109;20SECONDTARGET 198079199,64.1203,-59.3032,3.53,G05061;G05155;20SECONDTARGET # Sector 066 targets observed (2 min: 3, 20 s: 3) 22295632,268.2203,-41.9978,5.68,G05061;G05155;G05071;20SECONDTARGET 306980677,266.649,-62.7543,6.93,G05061;G05144;G05071;20SECONDTARGET 198079199,64.1203,-59.3032,3.53,G05061;G05155;20SECONDTARGET # Sector 067 targets observed (2 min: 2, 20 s: 2) 260795157,347.5869,-68.8368,7.73,G05061;G05144;G05071;20SECONDTARGET 260822727,348.4708,-68.2914,6.63,G05061;20SECONDTARGET # Sector 068 targets observed (2 min: 5, 20 s: 5) 147335048,325.7609,-43.4965,6.17,G05061;G05155;20SECONDTARGET 25300818,327.8549,-23.2711,6.38,G05061;G05155;20SECONDTARGET 260795157,347.5869,-68.8368,7.73,G05061;G05144;G05071;20SECONDTARGET 260822727,348.4708,-68.2914,6.63,G05061;20SECONDTARGET 198079199,64.1203,-59.3033,3.53,G05061;G05155;20SECONDTARGET # Sector 069 targets observed (2 min: 2, 20 s: 2) 220017951,32.6301,-50.8195,5.36,G05061;G05144;G05114;20SECONDTARGET 198079199,64.1203,-59.3033,3.53,G05061;G05155;20SECONDTARGET
