Updated Spitzer Emission Spectroscopy of Bright Transiting Hot Jupiter HD189733b
Kamen O. Todorov, Drake Deming, Adam S. Burrows +1
We analyze all existing secondary eclipse time series spectroscopy of hot Jupiter HD189733b acquired with the now defunct Spitzer/IRS instrument. We describe the novel approaches w…
Fixing the Reference Frame for PPMXL Proper Motions Using Extragalactic Sources
Kathleen Grabowski, Jeffrey L. Carlin, Heidi Jo Newberg +14
We quantify and correct systematic errors in PPMXL proper motions using extragalactic sources from the first two LAMOST data releases and the Veron-Cetty & Veron Catalog of Quasars…
Stacking the Invisibles: A Guided Search for Low-Luminosity Milky Way Satellites
B. Sesar, S. R. Banholzer, J. G. Cohen +9
Almost every known low-luminosity Milky Way dwarf spheroidal (dSph) satellite galaxy contains at least one RR Lyrae star. Assuming that a fraction of distant (60 < d_{helio} < 100…
Two New Halo Debris Streams in the Sloan Digital Sky Survey
Carl J. Grillmair
Using photometry from Data Release 10 of the northern footprint of the Sloan Digital Sky Survey, we detect two new stellar streams with lengths of between $25\arcdeg$ and $50\arcde…
Initial Performance of the NEOWISE Reactivation Mission
A. Mainzer, J. Bauer, R. M. Cutri +32
NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft has been brought out of hibernation and has resumed surveying the sky at 3.4 and 4.6 um. The scientific objectives of t…
IPAC Image Processing and Data Archiving for the Palomar Transient Factory
Russ R. Laher, Jason Surace, Carl J. Grillmair +26
The Palomar Transient Factory (PTF) is a multi-epochal robotic survey of the northern sky that acquires data for the scientific study of transient and variable astrophysical phenom…
