Context. It has been suggested that the helium absorption line at 10 830 Å that originates from the metastable triplet state 23S is an excellent probe for the extended atmospheres of hot Jupiters and their hydrodynamic escape processes. It has recently been detected in the transmission spectra of a handful of planets. The isotropic reem…

BepiColombo mission to Mercury: First year of flight
DOI: 10.1016/j.actaastro.2020.01.041 Bibcode: 2020AcAau.170..472S

Montagnon, Elsa; Ferri, Paolo; Accomazzo, Andrea +1 more

Launched in October 2018, the ESA/JAXA BepiColombo mission is set to arrive at Mercury in late 2025. The modular S/C consists of two scientific Mercury orbiters and a cruise module with electric propulsion to support the 7-years cruise phase with planetary flybys at Earth (1x), Venus (2x) and Mercury (6x). Flight operations of the composite spacec…

Massive Stars in the SDSS-IV/APOGEE2 Survey. III. New OB Stars in the Direction of the Sagittarius Spiral Arm
DOI: 10.3847/1538-4365/ab4bd7 Bibcode: 2020ApJS..247...17R

Minniti, Dante; Roman-Lopes, Alexandre; Tapia, Mauricio +2 more

We have applied the semi-empirical spectral analysis, developed by the Sloan Digital Sky Survey (SDSS)-IV/Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE2) Massive Star Team, to a large sample of new O- and B-type stars identified along the Sagittarius spiral arm, in the direction of the southern star clusters NGC3603 and NGC3576.…

Mars's Red (575-625 nm) Seasonal Approximate Reflectivity Averaged Over Mars Years 24-28 From Mars Orbiter Camera
DOI: 10.1029/2019JE006231 Bibcode: 2020JGRE..12506231R

Robbins, Stuart J.

The Mars Global Surveyor spacecraft successfully orbited Mars for over nine Earth years, its instruments returning a plethora of data that still today form important, key data sets in Mars research. A relatively underutilized data set was returned from the Mars Orbiter Camera (MOC), specifically the wide-angle component (MOC-WA), despite returning…

The Northern Extragalactic WISE × Pan-STARRS (NEWS) catalogue. Machine-learning identification of 40 million extragalactic objects
DOI: 10.1051/0004-6361/201834122 Bibcode: 2020A&A...644A..69K

Khramtsov, Vladislav; Akhmetov, Volodymyr; Fedorov, Peter

This study involves two photometric catalogues, AllWISE and Pan-STARRS Data Release 1, which were cross-matched to identify extragalactic objects among the common sources of these catalogues. To separate galaxies and quasars from stars, we created a machine-learning model that is trained on photometric (in fact, colour-based) information from the …

The Grism Lens-Amplified Survey from Space (GLASS) - XIII. G800L optical spectra from the parallel fields
DOI: 10.1093/mnras/staa276 Bibcode: 2020MNRAS.493..952A

Vulcani, B.; Treu, T.; Brammer, G. B. +5 more

We present a catalogue of 22 755 objects with slitless, optical, Hubble Space Telescope (HST) spectroscopy from the Grism Lens-Amplified Survey from Space (GLASS). The data cover ∼220 sq. arcmin to 7-orbit (∼10 ks) depth in 20 parallel pointings of the Advanced Camera for Survey's G800L grism. The fields are located 6 arcmin away from 10 massive g…

Mohan, S.; Saleem, M.; Resmi, L. +1 more

Advanced LIGO and Virgo (AdvLIGO/VIRGO) detectors reported the first binary neutron star merger candidate in the third observing run, S190425z, on 2019 April 25. A weak γ-ray excess was reported nearly coincidentally by the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite, which accidentally covered the entire localization regi…

Prospects for the In Situ detection of Comet C/2019 Y4 ATLAS by Solar Orbiter
DOI: 10.3847/2515-5172/ab8fa6 Bibcode: 2020RNAAS...4...62J

Afghan, Qasim; Jones, Geraint H.; Price, Oliver

The European Space Agency's Solar Orbiter spacecraft will pass approximately downstream of the position of comet C/2019 Y4 (ATLAS) in late May and early June 2020. We predict that the spacecraft may encounter the comet's ion tail around 2020 May 31—June 1, and that the comet's dust tail may be crossed on 2020 June 6. We outline the solar wind feat…

Observation of the Large-Amplitude and Fast-Damped Plasma Sheet Flapping Triggered by Reconnection-Induced Ballooning Instability
DOI: 10.1029/2020JA028218 Bibcode: 2020JGRA..12528218Z

Escoubet, C. P.; Dandouras, I.; Wang, C. +5 more

In this study, we reported the large-amplitude and fast-damped flapping of the plasma sheet, which co-occurred with magnetic reconnection. Data from the Double Star TC-1 and Cluster satellites were used to analyze the features of the plasma sheet flapping 1.4 RE earthward of an ongoing magnetic reconnection event. The flapping was rapid…
