Archival VLT/NaCo multiplicity investigation of exoplanet host stars
Jeremy Dietrich, Christian Ginski
Context: The influence of stellar multiplicity on planet formation is not yet well determined. Most planets are found using indirect detection methods via the small radial velocity…
High-Resolution SOFIA/EXES Spectroscopy of Gas in the Massive Young Stellar Object MonR2 IRS3: Implications for the Sulfur Budget
Ryan Dungee, Adwin Boogert, Curtis N. DeWitt +10
Sulfur has been observed to be severely depleted in dense clouds leading to uncertainty in the molecules that contain it and the chemistry behind their evolution. Here, we aim to s…
Detection of Nitrogen gas in the Pictoris circumstellar disk
P. A. Wilson, R. Kerr, A. Lecavelier des Etangs +4
The debris disk surrounding Pictoris has a gas composition rich in carbon and oxygen, relative to solar abundances. Two possible scenarios have been proposed to explain this en…
Meter- to Millimeter Emission from Cool Stellar Systems: Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade
Jan Forbrich, Peter K. G. Williams, Emily Drabek-Maunder +12
Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA,…
The ALMA Lupus protoplanetary disk survey: evidence for compact gas disks and molecular rings from CN
S. E. van Terwisga, E. F. van Dishoeck, P. Cazzoletti +10
The cyanide radical CN is abundant in protoplanetary disks, with line fluxes often comparable to those of CO. It is known to be sensitive to UV irradiation of the upper disk…
3D mapping of young stars in the solar neighbourhood with Gaia DR2
E. Zari, H. Hashemi, A. G. A. Brown +2
We study the three dimensional arrangement of young stars in the solar neighbourhood using the second release of the Gaia mission (Gaia DR2) and we provide a new, original view of…
The origin of the two populations of blue stragglers in M30
Simon Portegies Zwart
We analyze the position of the two populations of blue stragglers in the globular cluster M30 in the Hertzsprung-Russell diagram. Both populations of blue stragglers are brighter t…
The physical properties of AM CVn stars: new insights from Gaia DR2
G. Ramsay, M. J. Green, T. R. Marsh +9
AM CVn binaries are hydrogen deficient compact binaries with an orbital period in the 5-65 min range and are predicted to be strong sources of persistent gravitational wave radiati…
Gaps and Rings in an ALMA Survey of Disks in the Taurus Star-forming Region
Feng Long, Paola Pinilla, Gregory J. Herczeg +23
Rings are the most frequently revealed substructure in ALMA dust observations of protoplanetary disks, but their origin is still hotly debated. In this paper, we identify dust subs…
