High-resolution Imaging of Dust Shells Using Keck aperture Masking and the IOTA Interferometer
given current calibration software limitations
2014/12/24
We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array (IOTA) to image the circumstellar environments of evolved stars with …20 m...
Investigation of Herbig Ae /Be stars in the near -infrared with a long baseline interferometer
Long baseline Stars Near infrared interferometry The dust
2014/12/9
We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline spatial interferometry in the near-infrared, with the objective of characterizing the distributi...
Accurate Group Delay Measurement for Radial Velocity Instruments Using the Dispersed Fixed Delay Interferometer Method
Radial Velocity Dispersed Interferometer Method
2011/7/10
The Dispersed Fixed Delay Interferometer (DFDI) method is attractive for its low cost, compact size and multi-object capability in precision radial velocity (RV) measurements. The phase shift of fring...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/11
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star beta Cep using the spec...
QUBIC: The QU Bolometric Interferometer for Cosmology
Instrumentation and Methods for Astrophysics (astro-ph.IM)
