Anomalously low metallicity regions in MaNGA star-forming galaxies: Accretion Caught in Action?

Hsiang-Chih Hwang, Jorge K. Barrera-Ballesteros, Timothy M. Heckman +14

We use data from 1222 late-type star-forming galaxies in the SDSS IV MaNGA survey to identify regions in which the gas-phase metallicity is anomalously-low compared to expectations…

Predicting Granulation "Flicker" and Radial Velocity "Jitter" from Spectroscopic Observables

Jamie Tayar, Keivan G. Stassun, Enrico Corsaro

Surface granulation can be predicted with the mass, metallicity, and frequency of maximum power of a star. Using the orders-of-magnitude larger APOGEE-Kepler sample, we recalibrate…
