Constraining the Age-Activity Relation for Cool Stars: The Sloan Digital Sky Survey Data Release 5 Low-Mass Star Spectroscopic Sample
We present a spectroscopic analysis of over 38,000 low-mass stars from the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5). Analysis of this unprecedentedly large sample confirms the previouslyExpand
LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large SynopticExpand
We present a spectroscopic catalog of 70,841 visually inspected M dwarfs from the seventh data release of the Sloan Digital Sky Survey. For each spectrum, we provide measurements of the spectralExpand
Prospecting in late-type dwarfs: a calibration of infrared and visible spectroscopic metallicities of late-K and M dwarfs spanning 1.5 dex
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 stars is difficultExpand
Trumpeting M dwarfs with CONCH-SHELL: a catalogue of nearby cool host-stars for habitable exoplanets and life
We present an all-sky catalog of 2970 nearby (d . 50 pc), bright (J < 9) M- or late Ktype dwarf stars, 86% of which have been confirmed by spectroscopy. This catalog will be useful for searches forExpand
Kepler Flares I. Active and Inactive M dwarfs
We analyzed Kepler short-cadence M dwarf observations. Spectra from the ARC 3.5m telescope identify magnetically active (H$\alpha$ in emission) stars. The active stars are of mid-M spectral type,Expand
A Spectroscopic Catalog of the Brightest (J<9) M Dwarfs in the Northern Sky
We present a spectroscopic catalog of the 1564 brightest (J 40 mas yr{sup -1}) proper motion limit and high level of completeness of the SUPERBLINK catalog in that magnitude range, we estimate thatExpand
A contribution to the comparative osteology and phylogenetic systematics of fossil and living bony -tongue fishes (Actinopterygii, Teleostei, Osteoglossomorpha)
Osteoglossomorpha is supported by both synapomorphies and homoplasies, although its monophyly was not truly tested in this analysis (only a single outgroup, Elops , was included in the analysis). Expand
They Might be Giants: Luminosity Class, Planet Occurrence, and Planet–Metallicity Relation of the Coolest Kepler Target Stars
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). We determineExpand
Skeletal Anatomy of the Shortnose Sturgeon, Acipenser brevirostrum Lesueur, 1818, and the Systematics of Sturgeons (Acipenseriformes, Acipenseridae)
The skeletal anatomy of the shortnose sturgeon, Acipenser brevirostrum, is described and illustrated and the phylogenetic relationships of fossil and living acipenserids are studied, recovering †Chondrosteus as most basal amongAcipenseriformes rather than †Peipiaosteus. Expand
