The Sloan Digital Sky Survey (SDSS) has been in operation since 2000 April. This paper presents the Tenth Public Data Release (DR10) from its current incarnation, SDSS-III. This data release includes the first spectroscopic data from the Apache Point Observatory Galaxy Evolution Experiment (APOGEE), along with spectroscopic data from the Baryon Oscillation(More)
We present extensive early photometric (U BV Rr ′ Ii ′ JHK s) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data on the associated X-ray transient (XRT) 080109 which was serendipitously discovered in Swift data during follow-up observations of SN Ib 2007uy in the same galaxy, NGC 2770. Our data span a time range(More)
The explosion that results in a cosmic gamma-ray burst (GRB) is thought to produce emission from two physical processes: the central engine gives rise to the high-energy emission of the burst through internal shocking, and the subsequent interaction of the flow with the external environment produces long-wavelength afterglows. Although observations of(More)
We present high angular resolution observations with the Keck Interferometer, high dispersion spectroscopic observations with Keck/NIRSPEC, and near-IR photometric observations from PAIRITEL of a sample of 11 solar-type T Tauri stars in 9 systems. We use these observations to probe the circumstellar material within 1 AU of these young stars, measuring the(More)
We report the detection of eclipses in GJ 3236, a bright (I = 11.6) very low mass binary system with an orbital period of 0.77 days. Analysis of light-and radial velocity curves of the system yielded component masses of 0.38 ± 0.02 and 0.28 ± 0.02 M ⊙. The central values for the stellar radii are larger than the theoretical models predict for these masses,(More)
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis on the associated Swift X-ray transient (XRT) 080109. Our data span a time range of 5 hr before the detection of the X-ray transient to 150 days after its detection, and a(More)
We have obtained 1087 near-infrared (NIR; JHK s) measurements of 21 Type Ia supernovae (SNe Ia) using PAIRITEL, the 1.3-m Peters Automated InfraRed Imaging TELescope at Mount Hopkins, Arizona. This new set of observations nearly doubles the number of well-sampled NIR SN Ia light curves. These data strengthen the evidence that SNe Ia are excellent standard(More)
We present optical and infrared monitoring of the 2005 outburst of the halo black hole X-ray transient XTE J1118+480. We measured a total outburst amplitude of ∼ 5.7±0.1 mag in the R band and ∼ 5 mag in the infrared J, H and K s bands. The hardness ratio HR2 (5-12 keV/3-5 keV) from the RXTE/ASM data is 1.53±0.02 at the peak of the outburst indicating a hard(More)
We present light curves of the afterglow of GRB 050502A, including very early data at t À t GRB < 60 s. The light curve is composed of unfiltered ROTSE-IIIb optical observations from 44 s to 6 hr postburst, R-band MDM observations from 1.6 to 8.4 hr postburst, and PAIRITEL JHK s observations from 0.6 to 2.6 hr postburst. The optical light curve is fit by a(More)
