ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets
Finding Characterizing Exoplanets
2014/12/22
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 – 400 ìm wavelength range, a far-IR interferometer will revolutionize our understanding of planetary system format...
On the complementarity of pulsar timing and space laser interferometry for supermassive black hole binaries individual detection
complementarity pulsar timing space laser interferometry supermassive black hole
2011/10/14
For the observation of an individual supermassive black hole binary (SMBHB), the complementarity between pulsar timing (PT) and space laser interferometry (SLI) has been previously suggested. Herein s...
AMBER high-spectral resolution interferometry of Be stars: More than just stars and disks?
high-spectral resolution interferometry stars disks
2011/10/17
High spectral-resolution Br-gamma VLTI/AMBER observations of classical Be stars reveal complex visibility, phase, and closure phase profiles, which were not seen in previous lower-resolution data. The...
Mid-infrared interferometry of the massive young stellar object NGC 2264 IRS 1
techniques: interferometric - stars: individual: NGC 2264 IRS 1 - stars: formation-stars: circumstellar matter
2011/9/28
The optically invisible infrared-source NGC 2264 IRS 1 is thought to be a massive young stellar object (~10 Msun). Although strong infrared excess clearly shows that the central object is surrounded b...
Comparison of LISA and Atom Interferometry for Gravitational Wave Astronomy in Space
LISA and Atom Interferometry Gravitational Wave Astronomy Space
2011/9/14
One of the atom interferometer gravitational wave missions proposed by Dimopoulos et al.1 in 2008 was called AGIS-Sat. 2. It had a suggested gravitational wave sensitivity set by the atom state detect...
Hanbury Brown-Twiss interferometry and second-order correlations of inflaton quanta
Hanbury Brown-Twiss interferometry second-order correlations
2010/11/11
The quantum theory of optical coherence is applied to the scrutiny of the statistical
properties of the relic inflaton quanta. After adapting the description of the quantized scalar
and tensor modes...
Imaging "Pinwheel"nebulae with optical long-baseline interferometry
techniques high angular resolution – techniques interferometric – binaries close – stars
2010/11/16
Dusty Wolf-Rayet stars are few but remarkable in terms of dust production rates (up to ˙M = 10−6M⊙/yr). Infrared excesses associated to mass-loss are found in the sub-types WC8 and WC9. Few WC9d...
Images of unclassified and supergiant B[e] stars disks with interferometry
techniques high angular resolution – techniques interferometric – binaries close– stars
2010/11/16
B[e] stars are among the most peculiar objects in the sky. This spectral type, characterised
by allowed and forbidden emission lines, and a large infrared excess, does not represent an
homogenous cl...
The Space Interferometry Mission Astrometric Grid Giant-Star Survey. III. Basic Stellar Parameters for an Extended Sample
stars abundances fundamental parameters atmospheres latetype rotation
2010/11/10
We present results of high resolution ( 55000) spectral observations of 830 photometrically pre-selected candidate red giants in the magnitude range of V = 9-12. We develop a pipeline for automated d...
The exciting future of (sub-)millimeter interferometry: ALMA
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
The Atacama Large Millimeter/submillimeter Array (ALMA), presently under construction, is a revolutionary astronomical interferometer, that will operate at (sub)millimeter wavelengths. With unpreceden...
