Lithium depletion boundary, stellar associations, and Gaia
F. J. Galindo-Guil, D. Barrado, H. Bouy +9
Stellar ages are key to improving our understanding of different astrophysical phenomena. However, many techniques to estimate stellar ages are highly model-dependent. The lithium…
IGAPS: the merged IPHAS and UVEX optical surveys of theNorthern Galactic Plane
M. Monguió, R. Greimel, J. E. Drew +47
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003 an…
Evidence for optical pulsations from a redback millisecond pulsar
A. Papitto, F. Ambrosino, M. Burgay +16
Recent detections of optical pulsations from both a transitional and an accreting millisecond pulsar have revealed unexpectedly bright signals, suggesting that the presence of an a…
The GAPS Programme at TNG. XXIX. No detection of reflected light from 51 Peg b using optical high-resolution spectroscopy
G. Scandariato, F. Borsa, D. Sicilia +44
The analysis of exoplanetary atmospheres by means of high-resolution spectroscopy is an expanding research field which provides information on chemical composition, thermal structu…
Four ultra-short period eclipsing M-dwarf binaries in the WFCAM Transit Survey
S. V. Nefs, J. L. Birkby, I. A. G. Snellen +16
We report on the discovery of four ultra-short period (P<0.18 days) eclipsing M-dwarf binaries in the WFCAM Transit Survey. Their orbital periods are significantly shorter than of…
The GAPS Programme at TNG XXVII. Reassessment of a young planetary system with HARPS-N: is the hot Jupiter V830 Tau b really there?
M. Damasso, A. F. Lanza, S. Benatti +41
Detecting and characterising exoworlds around very young stars (age10 Myr) are key aspects of exoplanet demographic studies, especially for understanding the mechanisms and time…
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K-dwarf
J. L. Birkby, M. Cappetta, P. Cruz +34
We report the discovery of WTS-2 b, an unusually close-in 1.02-day hot Jupiter (Mp=1.12MJ, Rp=1.363RJ) orbiting a K2V star, which has a possible gravitationally-bound M-dwarf compa…
Discovery and characterisation of detached M-dwarf eclipsing binaries in the WFCAM Transit Survey
J. L. Birkby, S. V. Nefs, S. T. Hodgkin +17
We report the discovery of 16 detached M-dwarf eclipsing binaries with J<16 mag and provide a detailed characterisation of three of them, using high-precision infrared light curves…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Gaia Data Release 2: Observational Hertzsprung-Russell diagrams
Gaia Collaboration, C. Babusiaux, F. van Leeuwen +450
We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs, depending in partic…
Near-Earth asteroids spectroscopic survey at Isaac Newton Telescope
M. Popescu, O. Vaduvescu, J. de León +15
The population of near-Earth asteroids (NEAs) shows a large variety of objects in terms of physical and dynamical properties. They are subject to planetary encounters and to strong…
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
The GAPS Programme at TNG XXXIII. HARPS-N detects multiple atomic species in emission from the dayside of KELT-20b
F. Borsa, P. Giacobbe, A. S. Bonomo +31
The detection of lines in emission in planetary atmospheres provides direct evidence of temperature inversion. We confirm the trend of ultra-hot Jupiters orbiting A-type stars show…
The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
M. Cappetta, R. P. Saglia, J. L. Birkby +35
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in…
The GAPS Programme at TNG XLII. A characterisation study of the multi-planet system around the 400 Myr-old star HD 63433 (TOI-1726)
M. Damasso, D. Locci, S. Benatti +34
For more than two years, we monitored with the HARPS-N spectrograph the 400 Myr-old star HD\,63433, which hosts two close-in (orbital periods and days) s…
The GAPS Programme at TNG. XXXII. The revealing non-detection of metastable HeI in the atmosphere of the hot Jupiter WASP-80b
L. Fossati, G. Guilluy, I. F. Shaikhislamov +38
The hot Jupiter WASP-80b has been identified as a possible excellent target for detecting and measuring HeI absorption in the upper atmosphere. We observed 4 primary transits of WA…

Gaia Collaboration, F. van Leeuwen, A. Vallenari +589
Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry,…
