Clumpy structure in the debris disk around Vega has been previously reported at millimeter wavelengths and attributed to concentrations of dust grains trapped in resonances with an unseen planet. However, recent imaging at similar wavelengths with higher sensitivity has disputed the observed structure. We present three new millimeter wavelength observations that help to resolve the puzzling and contradictory observations. We have observed the Vega system with the Submillimeter Array (SMA) at a…

Resolved Millimeter-Wavelength Observations of Debris Disks around Solar-Type Stars
The presence of debris disks around young main sequence stars hints at the existence and structure of planetary systems. Millimeter-wavelength observations probe large grains that trace the location
MESAS: Measuring the Emission of Stellar Atmospheres at Submillimeter/millimeter Wavelengths
In the early stages of planet formation, small dust grains grow to become mm sized particles in debris disks around stars. These disks can in principle be characterized by their emission at
MILLIMETER EMISSION STRUCTURE IN THE FIRST ALMA IMAGE OF THE AU Mic DEBRIS DISK
We present 1.3 mm ALMA Cycle 0 observations of the edge-on debris disk around the nearby, similar to 10 Myr old, M-type star AU Mic. These observations obtain 0 ''.6 (6 AU) resolution and reveal two
Debris Disks in the Scorpius-Centaurus OB Association Resolved by ALMA
We present a CO(2-1) and 1240 um continuum survey of 23 debris disks with spectral types B9-G1, observed at an angular resolution of 0.5-1 arcsec with the Atacama Large Millimeter/Submillimeter Array
Resolved Imaging of the HR?8799 Debris Disk with Herschel
We present Herschel far-infrared and submillimeter maps of the debris disk associated with the HR 8799 planetary system. We resolve the outer disk emission at 70, 100, 160 and 250 µm and detect the
High-contrast imaging with Spitzer: deep observations of Vega, Fomalhaut, and ϵ Eridani
Stars with debris disks are intriguing targets for direct imaging exoplanet searches, owing both to previous detections of wide planets in debris disk systems. and to commonly existing morphological
Early science with the Large Millimetre Telescope: Deep LMT/AzTEC millimetre observations of ϵ Eridani and its surroundings
ǫ Eridani is a nearby, young Sun-like star that hosts a ring of cool debris analogous to the solar system’s Edgeworth-Kuiper belt. Early observations at (sub-)mm wave- lengths gave tentative
Debris disks around stars in the NIKA2 era
The new NIKA2 camera at the IRAM 30m radiotelescope was used to observe three known debris disks in order to constrain the SED of their dust emission in the millimeter wavelength domain. We have
ASTEROID BELTS IN DEBRIS DISK TWINS: VEGA AND FOMALHAUT
Vega and Fomalhaut are similar in terms of mass, ages, and global debris disk properties; therefore, they are often referred to as debris disk twins. We present Spitzer 10-35 micrometers
