The peculiar kinematics of the multiple populations in the globular cluster Messier 80 (NGC 6093)

Magnetic activity and evolution of the four Hyades K giants
Klaus-Peter Schröder, Marco Mittag, Dennis Jack +2
We determine the exact physical parameters of the four Hyades cluster K giants, using their parallaxes and atmospheric modeling of our red-channel TIGRE high-resolution spectra. Pe…
Differences in radio emission from similar M dwarfs in the binary system Ross 867-8

Sebastian Kamann, Benjamin Giesers, Nate Bastian +7
We investigate the binary content of the two stellar populations that coexist in the globular cluster NGC 3201. Previous studies of binary stars in globular clusters have reported…
VLBI observations of the G25.65+1.05 water maser superburst
R. A. Burns, G. Orosz, O. Bayandina +23
This paper reports observations of a 22 GHz water maser `superburst' in the G25.65+1.05 massive star forming region, conducted in response to an alert from the Maser Monitoring Org…
The dry and carbon poor inner disk of TW Hya: evidence for a massive icy dust trap
Arthur D. Bosman, Andrea Banzatti
Gas giants accrete their envelopes from the gas and dust of proto-planetary disks, so it is important to determine the composition of the inner few AU, where most giant planets are…
Demographics of disks around young very low-mass stars and brown dwarfs in Lupus
E. Sanchis, L. Testi, A. Natta +15
We present new 890 continuum ALMA observations of 5 brown dwarfs (BDs) with infrared excess in Lupus I and III -- which, in combination with 4 BDs previously observed, allowed…
Time-resolved photometry of the young dipper RX J1604.3-2130A: Unveiling the structure and mass transport through the innermost disk
A. Sicilia-Aguilar, C. F. Manara, J. de Boer +3
RX~J1604.3-2130A is a young, dipper-type, variable star in the Upper Scorpius association, suspected to have an inclined inner disk with respect to its face-on outer disk. We study…
Temperature profiles of young disk-like structures: The case of IRAS 16293A
Merel L. R. van 't Hoff, Ewine F. van Dishoeck, Jes K. Jørgensen +1
Temperature is a crucial parameter in circumstellar disk evolution and planet formation, because it governs the resistance of the gas to gravitational instability and sets the chem…
The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits
K. Perraut, L. Labadie, B. Lazareff +69
The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…
Bondi-Hoyle-Lyttleton accretion by binary stars
T. A. F. Comerford, R. G. Izzard, R. A. Booth +1
Binary stars often move through an ambient medium from which they accrete material and angular momentum, as in triple-star systems, star-forming clouds, young globular clusters and…
Spectral evolution and radial dust transport in the prototype young eruptive system EX Lup
Péter Ábrahám, Lei Chen, Ágnes Kóspál +7
EX Lup is the prototype of a class of pre-main sequence eruptive stars defined by their repetitive outbursts lasting several months. In 2008 January-September EX Lup underwent its…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
Chemical and kinematic structure of extremely high-velocity molecular jets in the Serpens Main star-forming region
Łukasz Tychoniec, Charles L. H. Hull, Lars E. Kristensen +3
The fastest molecular component to the protostellar outflows -- extremely high-velocity (EHV) molecular jets -- are still puzzling since they are seen only rarely. The first aim is…
Understanding the origin of the magnetic field morphology in the wide-binary protostellar system BHR 71
Charles L. H. Hull, Valentin J. M. Le Gouellec, Josep M. Girart +2
We present 1.3 mm ALMA observations of polarized dust emission toward the wide-binary protostellar system BHR 71 IRS1 and IRS2. IRS1 features what appears to be a natal, hourglass-…
The HH 212 interstellar laboratory: astrochemistry as a tool to reveal protostellar disks on Solar System scales around a rising Sun
Claudio Codella, Cecilia Ceccarelli, Chin-Fei Lee +8
The investigation of star forming regions have enormously benefited from the recent advent of the ALMA interferometer. More specifically, the unprecedented combination of high-sens…
Pulsations, eruptions, and evolution of four yellow hypergiants
A. M. van Genderen, A. Lobel, H. Nieuwenhuijzen +5
We aim to explore the variable photometric and stellar properties of four yellow hypergiants (YHGs), HR8752, HR 5171A, Cas, and HD 179821, and their pulsations of hundreds of d…
