Interferometric evidence for resolved warm dust in the DQ Tau system (2009)
Boden, Andrew F., Akeson, Rachel L., Sargent, Anneila I., Carpenter, John M., Ciardi, David R., Bary, Jeffrey S., ...
We report on near-infrared (IR) interferometric observations of the double-lined pre-main sequence binary system DQ Tau. We model these data with a visual orbit for DQ Tau supported by the...
Astrometry with the Keck-Interferometer: the ASTRA project and its science (2008)
Pott, Jorg-Uwe, Woillez, Julien, Akeson, Rachel L., Berkey, Ben, Colavita, Mark M., Cooper, Andrew, ...
The sensitivity and astrometry upgrade ASTRA of the Keck Interferometer is introduced. After a brief overview of the underlying interferometric principles, the technology and concepts of the upgrade...
Observations of circumstellar disks with infrared interferometry (2008)
The structure and composition of circumstellar disks around young stars is one of the areas in which infrared interferometry has had a major impact. I will review the observational progress in this...
Keck interferometer science : present and future (2008)
The Keck Interferometer is a NASA funded project developed by the Jet Propulsion Laboratory, the William M. Keck Observatory and the Michelson Science Center at the California Institute of...
Dynamical Masses for Pre-Main-Sequence Stars: A Preliminary Physical Orbit for V773 Tau A (2007)
Boden, Andrew F., Torres, Guillermo, Sargent, Anneila I., Akeson, Rachel L., Carpenter, John M., Boboltz, David A., ...
We report on interferometric and radial velocity observations of the double-lined 51 day period binary (A) component of the quadruple pre-main-sequence (PMS) system V773 Tau. With these observations...
Nulling at the Keck interferometer (2006)
Colavita, M. Mark, Serabyn, Gene, Wizinowich, Peter L., Akeson, Rachel L.
The nulling mode of the Keck Interferometer is being commissioned at the Mauna Kea summit. The nuller combines the two Keck telescope apertures in a split-pupil mode to both cancel the on-axis...
Keck Interferometer status and plans (2006)
Colavita, Mark M., Wizinowich, Peter L., Akeson, Rachel L.
Keck Interferometer is a NASA-funded project to combine the two 10 m Keck telescopes for high sensitivity near-infrared fringe visibility measurements, nulling interferometry at 10 µm to measure the...
Polarizing Grids, Their Assemblies and Beams of Radiation (2003)
Houde, Martin, Akeson, Rachel L., Carlstrom, John E., Lamb, James W., Schleuning, David A., Woody, David P.
This article gives an analysis of the behavior of polarizing grids and reflecting polarizers by solving Maxwell's equations, for arbitrary angles of incidence and grid rotation, for cases where the...
Protoplanetary Disk Mass Distribution in Young Binaries (2002)
Jensen, Eric L. N., Akeson, Rachel L.
We present millimeter-wave continuum images of four wide (separations 210-800 AU) young stellar binary systems in the Taurus-Auriga star-forming region. For all four sources, the resolution of our...
Altair's Oblateness and Rotation Velocity (2001)
Van Belle, Gerard T., Ciardi, David R., Thompson, Robert R., Akeson, Rachel L., Lada, Elizabeth A.
We present infrared interferometric angular size measurements for the A7IV-V star Altair which indicate a non-circular projected disk brightness distribution. Given the known rapid rotation of this...
On the Near-Infrared Size of Vega (2001)
Ciardi, David R., Van Belle, Gerard T., Akeson, Rachel L., Thompson, Robert R., Lada, Elizabeth A., Howell, Steve B.
Near-infrared (2.2 um) long baseline interferometric observations of Vega are presented. The stellar disk of the star has been resolved, and the data have been fitted with a limb darkened stellar...
