Nonequilibrium oscillations, probability angular momentum, and the climate system

Jeffrey B. Weiss, Baylor Fox-Kemper, Dibyendu Mandal +2

Though the Boltzmann-Gibbs framework of equilibrium statistical mechanics has been successful in many arenas, it is clearly inadequate for describing many interesting natural pheno…

SDSS-IV MaNGA: Evidence for enriched accretion onto satellite galaxies in dense environments

Adam L. Schaefer, Christy Tremonti, Zachary Pace +9

We investigate the environmental dependence of the local gas-phase metallicity in a sample of star-forming galaxies from the MaNGA survey. Satellite galaxies with stellar masses in…

Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper II: Applications of PCA-based stellar mass estimates

Zachary J. Pace, Christy Tremonti, Yanmei Chen +9

A galaxy's stellar mass is one of its most fundamental properties, but it remains challenging to measure reliably. With the advent of very large optical spectroscopic surveys, effi…

Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper I: PCA spectral fitting & stellar mass-to-light ratio estimates

Zachary J. Pace, Christy Tremonti, Yanmei Chen +9

We present a method of fitting optical spectra of galaxies using a basis set of six vectors obtained from principal component analysis (PCA) of a library of synthetic spectra of 40…

Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars IV: Updated Properties for 86 Cool Dwarfs Observed During Campaigns 1-17

Courtney D. Dressing, Kevin Hardegree-Ullman, Joshua E. Schlieder +15

We present revised stellar properties for 172 K2 target stars that were identified as possible hosts of transiting planets during Campaigns 1-17. Using medium-resolution near-infra…

K2-291 b: A rocky super-Earth in a 2.2 day orbit

Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43

K2-291 (EPIC 247418783) is a solar-type star with a radius of R_star = 0.899 0.034 R_sun and mass of M_star=0.934 0.038 M_sun. From K2 C13 data, we found one super-Eart…
