The Solar Neighborhood XLVII: Comparing M Dwarf Models with Hubble Space Telescope Dynamical Masses and Spectroscopy

Serge B. Dieterich, Andrew Simler, Todd J. Henry +1

We use HST/STIS optical spectroscopy of ten M dwarfs in five closely separated binary systems to test models of M dwarf structure and evolution. Individual dynamical masses ranging…

The Effect of Seafloor Weathering on Planetary Habitability

John Chambers

Conventionally, a habitable planet is one that can support liquid water on its surface. Habitability depends on temperature, which is set by insolation and the greenhouse effect, d…

Scaling laws for the geometry of an impact-induced magma ocean

Miki Nakajima, Gregor J. Golabek, Kai Wünnemann +6

Here, we develop scaling laws for (1) the distribution of impact-induced heat within the mantle and (2) shape of the impact-induced melt based on more than 100 smoothed particle hy…

The HOSTS survey for exozodiacal dust: Observational results from the complete survey

Steve Ertel, Denis Defrère, Philip M. Hinz +43

The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for fain…

Variable Accretion onto Protoplanet Host Star PDS 70

Thanawuth Thanathibodee, Brandon Molina, Nuria Calvet +6

The PDS 70 system has been subject to many studies in the past year following the discovery of two accreting planets in the gap of its circumstellar disk. Nevertheless, the mass ac…
