New radial velocity observations of AH Her: evidence for material outside the tidal radius
J. Echevarría, J. V. Hernández Santisteban, O. Segura Montero +7
Spectroscopic observations of AH Herculis during a deep quiescent state are put forward. We found the object in a rare long minima, allowing us to derive accurately the semi-amplit…
Lupus DANCe. Census of stars and 6D structure with Gaia-DR2 data
P. A. B. Galli, H. Bouy, J. Olivares +8
Context: Lupus is recognised as one of the closest star-forming regions, but the lack of trigonometric parallaxes in the pre-Gaia era hampered many studies on the kinematic propert…
Corona-Australis DANCe. I. Revisiting the census of stars with Gaia-DR2 data
P. A. B. Galli, H. Bouy, J. Olivares +5
Corona-Australis is one of the nearest regions to the Sun with recent and ongoing star formation, but the current picture of its stellar (and substellar) content is not complete ye…
Structure and kinematics of the Taurus star-forming region from Gaia-DR2 and VLBI astrometry
P. A. B. Galli, L. Loinard, H. Bouy +9
Aims:We take advantage of the second data release of the Gaia space mission and the state-of-the-art astrometry delivered from very long baseline interferometry observations to rev…
IC 4665 DANCe I. Members, empirical isochrones, magnitude distributions, present-day system mass function, and spatial distribution
N. Miret-Roig, H. Bouy, J. Olivares +12
Context. The study of star formation is extremely challenging due to the lack of complete and clean samples of young, nearby clusters, and star forming regions. The recent Gaia DR2…
Ruprecht 147 DANCe I. Members, empirical isochrone, luminosity and mass distributions
J. Olivares, H. Bouy, L. M. Sarro +10
Context. Ruprecht 147 is the oldest (2.5 Gyr) open cluster in the solar vicinity (< 300 pc), making it an important target for stellar evolution studies and exoplanet searches. Aim…
Extensive Photometry of V1838 Aql during the 2013 Superoutburst
J. Echevarría, E. de Miguel, J. V. Hernández Santisteban +15
We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A c…
The seven sisters DANCe IV. Bayesian hierarchical model
J. Olivares, L. M. Sarro, E. Moraux +8
Aims. We develop, test and characterise of a new statistical tool (intelligent system) for the sifting and analysis of nearby young open cluster (NYOC) populations. Methods. Using…
A revised moving cluster distance to the Pleiades open cluster
P. A. B. Galli, E. Moraux, H. Bouy +3
Aims: We provide a new distance estimate for the Pleiades based on the moving cluster method, which will be useful to further discuss the so-called Pleiades distance controversy an…
Messier 35 (NGC2168) DANCe I. Membership, proper motions and multi-wavelength photometry
H. Bouy, E. Bertin, D. Barrado +7
We aim at identifying the cluster's members by deriving membership probabilities for the sources within 1 degree of the cluster's center, going further away than equivalent previou…
Kinematics of the Orion Trapezium Based on Diffracto-Astrometry and Historical Data
J. Olivares, L. J. Sánchez, A. Ruelas-Mayorga +3
Using the novel Diffracto-Astrometry technique, we analyze 44 Hubble Space Telescope Wide Field Planetary Camera 2 images of the Orion Trapezium (OT) taken over a span of 12 yr (19…
