We collect a sample of stars observed both in LAMOST and Gaia which have colors implying a temperature hotter than 7000 K. We train a machine learning algorithm on LAMOST spectroscopic data which has been tagged with stellar classifications and metal

We calculate the ages, orbits and phase-space coordinates for a sample of $\sim$4 million LAMOST and Gaia stars. The ages are crossmatched and compared with values from two other popular age catalogs which derive the ages using different methods. Of

In this paper we investigate how the chemical and kinematic properties of stars vary as a function of age. Using data from a variety of photometric, astrometric and spectroscopic surveys, we calculate the ages, phase space information and orbits for

We discuss the selection of blue horizontal branch stars (BHBs) using preliminary Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) color data and outline techniques for structure detection using those data. We first outline the adapt

In this paper we notice that extragalactic sources seem to have non-zero proper motions in the PPMXL proper motion catalog. We collect a large, all-sky sample of extragalactic objects and fit their reported PPMXL proper motions to an ensemble of sphe

Ramsey's "Facts and Propositions" is terse, allusive, and dense. The paper is far from easy to understand. The present essay is an effort, largely following Brian Loar's account,' to say what Ramsey's goal is, to spell out what he took to be the mean

For forty years on either side of the death of John Wesley in 1791, Thomas Coke was a key figure in the development of Methodism on both sides of the Atlantic. His surviving correspondence is the most personal evidence he has left us of a man who “

Ever since John Wesley departed from Anglican usage by'consecrating'him as Superintendent of American Methodism, Thomas Coke has been a center of controversy. Though remembered primarily as the'Father of Methodist missions,'he was a key figure in the
