Infrared study of transitional disks in Ophiuchus with Herschel
Isabel Rebollido, Bruno MerÃn, Ãlvaro Ribas +7
Context. Observations of nearby star-forming regions with the Herschel Space Observatory complement our view of the protoplanetary disks in Ophiuchus with information about the out…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
Large Projects in Astronomy: An Indian Endeavour
Yogesh Wadadekar, Shriharsh Tendulkar, Sanjit Mitra +6
Policy Brief on "Large Projects in Astronomy: An Indian Endeavour", distilled from the corresponding panel that was part of the discussions during S20 Policy Webinar on Astroinform…
Ruling out unresolved binaries in five transitional disks VLT/NACO: deep 2.12 and 1.75 μm narrow-band imaging
Silvia Vicente, Bruno Merın, Markus Hartung +8
Aims. We aim at detecting the presence of companions inside the inner hole/gap region of a sample of five well known transitional disks using spatially-resolved imaging in the near…
The 800pc long tidal tails of the Hyades star cluster: Possible discovery of candidate epicyclic overdensities from an open star cluster
Tereza Jerabkova, Henri M. J. Boffin, Giacomo Beccari +3
The tidal tails of stellar clusters provide an important tool for studying the birth conditions of the clusters and their evolution, coupling, and interaction with the Galactic pot…
A Spitzer c2d Legacy Survey to Identify and Characterize Disks with Inner Dust Holes
Bruno MerÃn, Joanna M. Brown, Isa Oliveira +17
Understanding how disks dissipate is essential to studies of planet formation. However, identifying exactly how dust and gas dissipates is complicated due to difficulty in finding…
AstroInformatics: Recommendations for Global Cooperation
Ashish Mahabal, Pranav Sharma, Rana Adhikari +45
Policy Brief on "AstroInformatics, Recommendations for Global Collaboration", distilled from panel discussions during S20 Policy Webinar on Astroinformatics for Sustainable Develop…
Finding the dispersing siblings of young open clusters. Dynamical traceback simulations using Gaia DR3
Eero Vaher, David Hobbs, Paul McMillan +1
Context. Stars tend to form in clusters, but many escape their birth clusters very early. Identifying the escaped members of clusters can inform us about the dissolution of star cl…
Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
The outbursting protostar 2MASS~22352345+7517076 and its environment
Maria Kun, Peter Abraham, Jose Antonio Acosta Pulido +2
We studied the Class I protostar 2MASS 22352345+7517076 whose dramatic brightening between the IRAS, Akari, and WISE surveys was reported by Onozato et al. (2015). 2MASS 22352345+7…
VISIONS: The VISTA Star Formation Atlas -- I. Survey overview
Stefan Meingast, João Alves, Hervé Bouy +37
VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Aus…
A revised estimate of the distance to the clouds in the Chamaeleon complex using the Tycho-Gaia Astrometric Solution
Jordan Voirin, Carlo F. Manara, Timo Prusti
The determination of the distance to dark star-forming clouds is a key parameter to derive the properties of the cloud itself, and of its stellar content. This parameter is still l…
Long-term infrared variability of the UX Ori-type star SV Cep
Attila Juhasz, Timo Prusti, Peter Abraham +1
We investigate the long-term optical-infrared variability of SV Cep, and explain it in the context of an existing UX Ori (UXOR) model. A 25-month monitoring programme was completed…
