Y dwarf Trigonometric Parallaxes from the Spitzer Space Telescope
Emily C. Martin, J. Davy Kirkpatrick, Charles A. Beichman +12
Y dwarfs provide a unique opportunity to study free-floating objects with masses 30 M and atmospheric temperatures approaching those of known Jupiter-like exoplanets. Ob…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
A near-infrared interferometric survey of debris-disc stars. V. PIONIER search for variability
S. Ertel, D. Defrère, O. Absil +10
Context: Extended circumstellar emission has been detected within a few 100 milli-arcsec around > 10% of nearby main sequence stars using near-infrared interferometry. Follow-up ob…
Searching for faint companions with VLTI/PIONIER. II. 92 main sequence stars from the Exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +6
The Exozodi survey aims to determine the occurrence rate of bright exozodiacal discs around nearby main sequence stars using infrared interferometry. Although the Exozodi survey ta…
An independent determination of Fomalhaut b's orbit and the dynamical effects on the outer dust belt
Hervé Beust, Jean-Charles Augereau, Amy Bonsor +7
The nearby star Fomalhaut harbours a cold, moderately eccentric dust belt with a sharp inner edge near 133 au. A low-mass, common proper motion companion (Fom b), was discovered ne…
DUst Around NEarby Stars. The survey observational results
C. Eiroa, J. P. Marshall, A. Mora +47
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
An interferometric study of the Fomalhaut inner debris disk II. Keck Nuller mid-infrared observations
B. Mennesson, O. Absil, J. Lebreton +7
We report on high contrast mid-infrared observations of Fomalhaut obtained with the Keck Interferometer Nuller (KIN) showing a small resolved excess over the level expected from th…
HD 172555: detection of 63 microns [OI] emission in a debris disc
P. Riviere-Marichalar, D. Barrado, J. -C. Augereau +14
Context. HD 172555 is a young A7 star belonging to the Beta Pictoris Moving Group that harbours a debris disc. The Spitzer IRS spectrum of the source showed mid-IR features such as…
A peculiar class of debris disks from Herschel/DUNES - A steep fall off in the far infrared
S. Ertel, S. Wolf, J. P. Marshall +21
Aims. We present photometric data of debris disks around HIP 103389 (HD 199260), HIP 107350 (HN Peg, HD206860), and HIP 114948 (HD 219482), obtained in the context of our Herschel…
Herschel discovery of a new class of cold, faint debris discs
C. Eiroa, J. P. Marshall, A. Mora +25
We present Herschel PACS 100 and 160 micron observations of the solar-type stars alpha Men, HD 88230 and HD 210277, which form part of the FGK stars sample of the Herschel Open Tim…
Deep near-infrared interferometric search for low-mass companions around beta Pictoris
Olivier Absil, Jean-Baptiste Le Bouquin, Jeremy Lebreton +6
Aims. We search for low-mass companions in the innermost region (<300 mas, i.e., 6 AU) of the beta Pic planetary system. Methods. We obtained interferometric closure phase measurem…
Gas in Protoplanetary Discs (GASPS) 1. First results
G. S. Mathews, W. R. F. Dent, J. P. Williams +50
Context - Circumstellar discs are ubiquitous around young stars, but rapidly dissipate their gas and dust on timescales of a few Myr. The Herschel space observatory allows for the…
Starspot Jitter in Photometry, Astrometry and Radial Velocity Measurements
V. V. Makarov, C. A. Beichman, J. H. Catanzarite +4
Analytical relations are derived for the amplitude of astrometric, photometric and radial velocity perturbations caused by a single rotating spot. The relative power of the star sp…
