Flattened, rotating disks of cool dust and gas extending for tens to hundreds of astronomical
units are found around almost all low-mass stars shortly after their birth. These disks …

Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

BANYAN Σ is a new Bayesian algorithm to identify members of young stellar associations
within 150 pc of the Sun. It includes 27 young associations with ages in the range∼ 1–800 …

Abstract We introduce the Ophiuchus DIsc Survey Employing ALMA (ODISEA), a project
aiming to study the entire population of Spitzer-selected protoplanetary discs in the …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

Circumstellar disks are thought to experience a rapid" transition" phase in their evolution that
can have a considerable impact on the formation and early development of planetary …

We present 1.3 mm continuum ALMA long-baseline observations at 3–5 au resolution of 10
of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project …

Context. The planet-forming region of protoplanetary disks is cold, dense, and therefore
weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be …

Aims. We study the dependence of protoplanetary disk evolution on stellar mass using a
large sample of young stellar objects in nearby young star-forming regions. Methods. We …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …
