The Information Content in Analytic Spot Models of Broadband Precision Lightcurves
Lucianne M. Walkowicz, Gibor S. Basri, Jeff A. Valenti
We present the results of numerical experiments to assess degeneracies in lightcurve models of starspots. Using synthetic lightcurves generated with the Cheetah starspot modeling c…
ASTEP South: a first photometric analysis
N. Crouzet, T. Guillot, D. Mékarnia +20
The ASTEP project aims at detecting and characterizing transiting planets from Dome C, Antarctica, and qualifying this site for photometry in the visible. The first phase of the pr…
Exploring the NRO Opportunity for a Hubble-sized Wide-field Near-IR Space Telescope -- NEW WFIRST
Alan Dressler, David Spergel, Matt Mountain +24
We discuss scientific, technical and programmatic issues related to the use of an NRO 2.4m telescope for the WFIRST initiative of the 2010 Decadal Survey. We show that this impleme…
The ASTRO-H X-ray Observatory
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +220
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
The Multi-Object, Fiber-Fed Spectrographs for SDSS and the Baryon Oscillation Spectroscopic Survey
Stephen Smee, James E. Gunn, Alan Uomoto +61
We present the design and performance of the multi-object fiber spectrographs for the Sloan Digital Sky Survey (SDSS) and their upgrade for the Baryon Oscillation Spectroscopic Sur…
Detection and Characterization of Exoplanets and Disks using Projections on Karhunen-Loeve Eigenimages
Remi Soummer, Laurent Pueyo, James Larkin
We describe a new method to achieve point spread function (PSF) subtractions for high- contrast imaging using Principal Component Analysis (PCA) that is applicable to both point so…
