Investigating Exoplanet System Trends at the M Dwarf Convective Boundary

Mon/Tue, July 4-5, 2022 and Online | Poster #140

Using Gaia Data Release 2, Jao et al. (2018) identified an underdensity of stars marking the boundary between partially and fully convective M dwarfs. Low-mass stars in this “gap” feature of the HR diagram slowly expand and contract for up to billions of years, leading to luminosity changes, before settling as fully convective M dwarfs. Although a similar brightening of the Sun could send the Earth into a moist runaway greenhouse state, there has been little investigation into the relationship between the unique history of gap M dwarfs and the formation and evolution of their planetary systems. To search for defining features in systems in this recently discovered area of phase space, we obtain information on the stars and planets from Gaia DR2 and the NASA Exoplanet Archive. We probe key exoplanet system properties including radius, period, and multiplicity. Here we present the first results of our search for trends in these properties for several dozen confirmed exoplanet systems associated with the gap.
