Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

The characterization of exoplanets and their birth protoplanetary disks has enormously
advanced in the last decade. Benefitting from that, our global understanding of the planet …

We propose a new simple formalism to predict the orbital separations after common-
envelope phases with massive-star donors. We focus on the fact that massive red …

Recent spatially-resolved observations of protoplanetary disks revealed a plethora of
substructures, including concentric rings and gaps, inner cavities, misalignments, spiral …

The detection of a wide range of substructures such as rings, cavities, and spirals has
become a common outcome of high spatial resolution imaging of protoplanetary disks, both …

High-spatial-resolution observations of CO isotopologue line emission in protoplanetary
disks at mid-inclinations (≈ 30–75) allow us to characterize the gas structure in detail …

We present high-resolution millimeter continuum ALMA observations of the disks around the
T Tauri stars LkCa 15 and 2MASS J16100501-2132318 (hereafter, J1610). These transition …

The volatile contents of protoplanetary disks both set the potential for planetary chemistry
and provide valuable probes of defining disk system characteristics such as stellar mass …

We present deep high-resolution (∼ 50 mas, 8 au) Atacama Large Millimeter/submillimeter
Array (ALMA) 0.88 and 1.3 mm continuum observations of the LkCa 15 disk. The emission …

Context. The total disk gas mass and elemental C, N, and O composition of protoplanetary
disks are crucial ingredients for improving our understanding of planetary formation …
