Objects in Kepler's Mirror May be Larger Than They Appear: Bias and Selection Effects in Transiting Planet Surveys
Eric Gaidos, Andrew W. Mann
Statistical analyses of large surveys for transiting planets such as the Kepler mission must account for systematic errors and biases. Transit detection depends not only on the pla…
Prospecting in late-type dwarfs: a calibration of infrared and visible spectroscopic metallicities of late-K and M dwarfs spanning 1.5 dex
Andrew W. Mann, John M. Brewer, Eric Gaidos +2
Knowledge of late K and M dwarf metallicities can be used to guide planet searches and constrain planet formation models. However, the determination of metallicities of late-type s…
LHS 2803B: A very wide mid-T dwarf companion to an old M dwarf identified from Pan-STARRS1
Niall R. Deacon, Michael C. Liu, Eugene A. Magnier +12
We report the discovery of a wide (approximately 400 AU projected separation), common proper motion companion to the nearby M dwarf LHS 2803 (PSO J207.0300-13.7422). This object wa…
A Spectroscopic Catalog of the Brightest (J<9) M Dwarfs in the Northern Sky
Sebastien Lepine, Eric J. Hilton, Andrew W. Mann +4
We present a spectroscopic catalog of the 1,564 brightest (J<9) M dwarf candidates in the northern sky, as selected from the SUPERBLINK proper motion catalog. Observations confirm…
They might be giants: luminosity class, planet frequency, and planet-metallicity relation of the coolest Kepler target stars
Andrew W. Mann, Eric Gaidos, Sébastien Lépine +1
We estimate the stellar parameters of late K and early M type Kepler target stars. We obtain medium resolution visible spectra of 382 stars with Kp-J>2 (~K5 and later spectral type…
