The characterization of the dust content in the ring around Sz 91: indications of planetesimal formation?
(IOP, 2021)
One of the most important questions in the field of planet formation is how millimeter- and centimeter-sized dust
particles overcome radial drift and fragmentation barriers to form kilometer-sized planetesimals. ...
Molecules with ALMA at Planet-forming Scales (MAPS). I. Program overview and highlights
(IOP, 2021)
Planets form and obtain their compositions in dust- and gas-rich disks around young stars, and the outcome of this process is intimately linked to the disk chemical properties. The distributions of molecules across disks ...
A tale of two transition disks: alma long-baseline observations of iso-oph 2 reveal two closely packed nonaxisymmetric rings and a similar to 2 au cavity
(IOP Publishing, 2020)
ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M-dust similar to 40M(circle plus)) ring-like disk with a dust cavity similar to 50 au in radius and the secondary hosts a ...
Molecules with ALMA at Planet-forming Scales (MAPS). II. Clean strategies for synthesizing images of molecular line emission in protoplanetary disks
(IOP, 2021)
The Molecules with ALMA at Planet-forming Scales Large Program (MAPS LP) surveyed the chemical structures of five protoplanetary disks across more than 40 different spectral lines at high angular resolution (0.'' 15 and ...
The HASHTAG Project: the first submillimeter images of the Andromeda Galaxy from the Ground
(IOP, 2021)
Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths compared to the brightness at the peak of the ...
