He Abundances in Planetary Nebulae
Lizette Guzman-Ramirez
The He isotope is important to many fields of astrophysics, including stellar evolution, chemical evolution, and cosmology. The isotope is produced in stars which evolve throug…
Lupus disks with faint CO isotopologues: low gas/dust or large carbon depletion?
Anna Miotello, Ewine F. van Dishoeck, Jonathan P. Williams +8
An era has started in which gas and dust can be observed independently in protoplanetary disks, thanks to the recent surveys with ALMA. The first near-complete high-resolution disk…

J. M. Lykke, A. Coutens, J. K. Jørgensen +14
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed. Aims. Our aim is to start the process of compiling an inventory of oxygen-bea…
The Gould's Belt Distances Survey (GOBELINS) I. Trigonometric parallax distances and depth of the Ophiuchus complex
Gisela N. Ortiz-León, Laurent Loinard, Marina A. Kounkel +14
We present the first results of the Gould's Belt Distances Survey (GOBELINS), a project aimed at measuring the proper motion and trigonometric parallax of a large sample of young s…
A Chemical Composition Survey of the Iron-Complex Globular Cluster NGC 6273 (M 19)
Christian I. Johnson, Nelson Caldwell, R. Michael Rich +5
Recent observations have shown that a growing number of the most massive Galactic globular clusters contain multiple populations of stars with different [Fe/H] and neutron-capture…
Radio Measurements of the stellar proper motions in the core of the Orion Nebula Cluster
Sergio A. Dzib, Laurent Loinard, Luis F. Rodríguez +8
Using multi-epoch VLA observations, covering a time baseline of 29.1 years, we have measured the proper motions of 88 young stars with compact radio emission in the core of the Ori…
A "Rosetta Stone" for protoplanetary disks: The synergy of multi-wavelength observations
A. Sicilia-Aguilar, A. Banzatti, A. Carmona +7
The recent progress in instrumentation and telescope development has brought us different ways to observe protoplanetary disks, including interferometers, space missions, adaptive…
The ALMA Early Science view of FUor/EXor objects. I. Through the looking-glass of V2775 Ori
Alice Zurlo, Lucas A. Cieza, Jonathan P. Williams +11
As part of an ALMA survey to study the origin of episodic accretion in young eruptive variables, we have observed the circumstellar environment of the star V2775 Ori. This object i…
A Triple Protostar System Formed via Fragmentation of a Gravitationally Unstable Disk
John Tobin, Kaitlin Kratter, Magnus Persson +9
Binary and multiple star systems are a frequent outcome of the star formation process, and as a result, almost half of all sun-like stars have at least one companion star. Theoreti…
Robustness of N2H+ as tracer of the CO snowline
Merel L. R. van 't Hoff, Catherine Walsh, Mihkel Kama +2
[Abridged] Snowlines in protoplanetary disks play an important role in planet formation and composition. Since the CO snowline is difficult to observe directly with CO emission, it…
Misaligned Disks in the Binary Protostar IRS 43
Christian Brinch, Jes K. Jørgensen, Michiel R. Hogerheijde +2
Recent high angular resolution (0.2") ALMA observations of the 1.1 mm continuum and of HCO+ J=3-2 and HCN J=3-2 gas towards the binary protostar IRS 43 reveal multiple Kepler…
The Gould's Belt Distances Survey (GOBELINS) III. The distance to the Serpens/Aquila Molecular Complex
Gisela N. Ortiz-León, Sergio A. Dzib, Marina A. Kounkel +12
We report on new distances and proper motions to seven stars across the Serpens/Aquila complex. The observations were obtained as part of the Gould's Belt Distances Survey (GOBELIN…
The Gould's Belt Distances Survey (GOBELINS) II. Distances and structure towards the Orion Molecular Clouds
Marina Kounkel, Lee Hartmann, Laurent Loinard +12
We present the results of the Gould's Belt Distances Survey (GOBELINS) of young star forming regions towards the Orion Molecular Cloud Complex. We detected 36 YSOs with the Very La…
The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
The link between solenoidal turbulence and slow star formation in G0.253+0.016
C. Federrath, J. M. Rathborne, S. N. Longmore +8
Star formation in the Galactic disc is primarily controlled by gravity, turbulence, and magnetic fields. It is not clear that this also applies to star formation near the Galactic…
The disappearing act: A dusty wind eclipsing RW Aur
I. Bozhinova, A. Scholz, G. Costigan +8
RW Aur is a young binary star that experienced a deep dimming in 2010-11 in component A and a second even deeper dimming from summer 2014 to summer 2016. We present new unresolved…
Spin equilibrium in strongly-magnetized accreting stars
Caroline D'Angelo
Strongly magnetized accreting stars are often hypothesized to be in `spin equilibrium' with their surrounding accretion flows, which requires that the accretion rate changes more s…
A gas density drop in the inner 6 AU of the transition disk around the Herbig Ae star HD 139614: Further evidence for a giant planet inside the disk?
A. Carmona, W. F. Thi, I. Kamp +16
Context: Quantifying the gas content inside the dust gaps of transition disks is important to establish their origin. Aims: We seek to constrain the surface density of warm gas in…
Mass measurements in protoplanetary disks from hydrogen deuteride
Melissa McClure, Ted Bergin, Ilse Cleeves +8
The total gas mass of a protoplanetary disk is a fundamental, but poorly determined, quantity. A new technique \citep{bergin+13} has been demonstrated to assess directly the bulk m…
The evolutionary status of dense cores in the NGC 1333 IRAS 4 region
E. Koumpia, F. F. S. van der Tak, W. Kwon +3
