Dust evolution during protoplanetary disk buildup enhances CO ice relative to water
Astronomy & AstrophysicsContext. Water ice is expected to be the dominant volatile component of bodies formed in the outer Solar System. However, recent observations of comets and trans-Neptunian objects suggest that the relative abundances of ices can vary substantially, with ...

The Dispersal of Planet-forming discs: Theory confronts Observations
, 2017 Discs of gas and dust around Myr-old stars are a by-product of the star formation process and provide the raw material to form planets. Hence, their evolution and dispersal directly impact what type of planets can form and affect the final architecture ...

The Astrophysical JournalThe inward drift of millimeter–centimeter sized pebbles in protoplanetary disks has become an important part of our current theories of planet formation and, more recently, planet composition as well.

Light Echoes of Time-resolved Flares and Application to Kepler Data
The Open Journal of AstrophysicsLight echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

SMA and NOEMA Reveal Asymmetric Substructure in the Protoplanetary Disk of IRAS 23077+6707
The Astrophysical JournalWe present high-resolution data of IRAS 23077+6707 (“ Dracula’s Chivito ”) with the Submillimeter Array (SMA at 1.33 mm/225.5 GHz) and the Northern Extended Millimeter Array (NOEMA at 2.7 mm/111.7 GHz and 3.1 mm/96.2 GHz).

The Structure and Evolution of Protoplanetary Disks: an infrared and submillimeter view
, 2015 Circumstellar disks are the sites of planet formation, and the very high incidence of extrasolar planets implies that most of them actually form planetary systems.

Radial and Vertical Constraints on the Icy Origin of H2CO in the HD 163296 Protoplanetary Disk
The Astrophysical JournalH _2 CO is a small organic molecule widely detected in protoplanetary disks. As a precursor to grain-surface formation of CH _3 OH, H _2 CO is considered an important precursor of O-bearing organic molecules that are locked in ices.

A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues
The Astrophysical Journal LettersDespite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseous envelopes that are warmer than the surrounding disk gas, potentially ...
