I spy a planet: the impact of stellar variability on microlensing

PI: Newton, Elisabeth, Dartmouth CollegeWide-Field Science – Regular M dwarfs are the most common type of star in our Galaxy, with the stellar mass function peaking around 0.23M☉ or T* = 3200 K (M4V). Given Roman’s deep sensitivity, these stars will dominate both the sources and lenses of exoplanet microlensing events observed in Roman’s Galactic […] The post I spy a planet: the impact of stellar variability on microlensing appeared first on NASA Science.
