Astrometric Detection of exo-Earths in the Presence of Stellar Noise
Joseph Catanzarite, Nicholas Law, Michael Shao
Space astrometry is capable of sub-microarcsecond measurements of star positions. A hundred visits over several years could yield relative astrometric precision of ~0.1 uas, below…
Overview of the SIM PlanetQuest Light (SIM-Lite) mission concept
R. Goullioud, J. H. Catanzarite, F. G. Dekens +2
The Space Interferometry Mission PlanetQuest Light (or SIM-Lite) is a new concept for a space borne astrometric instrument, to be located in a solar Earth-trailing orbit. SIM-Lite…
Taking the Measure of the Universe: Precision Astrometry with SIM PlanetQuest
Stephen C. Unwin, Michael Shao, Angelle M. Tanner +33
Precision astrometry at microarcsecond accuracy has application to a wide range of astrophysical problems. This paper is a study of the science questions that can be addressed usin…
SIM PlanetQuest: The Most Promising Near-Term Technique to Detect, Find Masses, and Determine Three-Dimensional Orbits of Nearby Habitable Planets
M. Shao, G. Marcy, S. Unwin +21
The past two Decadal Surveys in Astronomy and Astrophysics recommended the completion of a space-based interferometry mission, known today as SIM PlanetQuest, for its unique abilit…
Astrometric Detection of Terrestrial Planets in the Habitable Zones of Nearby Stars with SIM PlanetQuest
Joseph Catanzarite, Michael Shao, Angelle Tanner +2
SIM PlanetQuest (Space Interferometry Mission) is a space-borne Michelson interferometer for precision stellar astrometry, with a nine meter baseline, currently slated for launch i…
Altair: The Brightest Delta Scuti Star
D. L. Buzasi, H. Bruntt, T. R. Bedding +7
We present an analysis of observations of the bright star Altair (alpha Aql) obtained using the star camera on the Wide-Field Infrared Explorer (WIRE) satellite. Although Altair li…
