DOI: 10.1051/0004-6361/201937381 Bibcode: 2020A&A...637A..38P

Tremblin, P.; Allard, N. F.; Baraffe, I. +6 more

We present a new set of solar metallicity atmosphere and evolutionary models for very cool brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere models are generated with our state-of-the-art 1D radiative-convective equilibrium code ATMO, and are used as surface boundary conditions to calculate the interior structure…

The Atacama Large Millimeter Array (ALMA) Large Program to INvestigate [CII] at Early times (ALPINE) targets the [CII] 158 µm line and the far-infrared continuum in 118 spectroscopically confirmed star-forming galaxies between z = 4.4 and z = 5.9. It represents the first large [CII] statistical sample built in this redshift range. We present…

André, N.; Fedorov, A.; Livi, S. +126 more

The Solar Orbiter mission seeks to make connections between the physical processes occurring at the Sun or in the solar corona and the nature of the solar wind created by those processes which is subsequently observed at the spacecraft. The mission also targets physical processes occurring in the solar wind itself during its journey from its sourc…

The ALPINE-ALMA [CII] survey. Survey strategy, observations, and sample properties of 118 star-forming galaxies at 4 < z < 6
DOI: 10.1051/0004-6361/201936965 Bibcode: 2020A&A...643A...1L

Cimatti, A.; Maiolino, R.; Pozzi, F. +43 more

The ALMA-ALPINE [CII] survey is aimed at characterizing the properties of a sample of normal star-forming galaxies (SFGs). The ALMA Large Program to INvestigate (ALPINE) features 118 galaxies observed in the [CII]-158 µm line and far infrared (FIR) continuum emission during the period of rapid mass assembly, right after the end of the HI rei…

Planck 2018 results. XII. Galactic astrophysics using polarized dust emission
DOI: 10.1051/0004-6361/201833885 Bibcode: 2020A&A...641A..12P

Kim, J.; Miville-Deschênes, M. -A.; Boulanger, F. +160 more

Observations of the submillimetre emission from Galactic dust, in both total intensity I and polarization, have received tremendous interest thanks to the Planck full-sky maps. In this paper we make use of such full-sky maps of dust polarized emission produced from the third public release of Planck data. As the basis for expanding on astrophysica…

The Solar Orbiter magnetometer
DOI: 10.1051/0004-6361/201937257 Bibcode: 2020A&A...642A...9H

Russell, C. T.; Forsyth, R.; Müller, D. +49 more

The magnetometer instrument on the Solar Orbiter mission is designed to measure the magnetic field local to the spacecraft continuously for the entire mission duration. The need to characterise not only the background magnetic field but also its variations on scales from far above to well below the proton gyroscale result in challenging requiremen…

Planetary nebulae seen with TESS: Discovery of new binary central star candidates from Cycle 1
DOI: 10.1051/0004-6361/201937118 Bibcode: 2020A&A...635A.128A

Lillo-Box, J.; Jones, D.; Miranda, L. F. +2 more

Context. It has become clear in recent years that binarity plays a crucial role in many aspects of planetary nebulae (PNe), particularly with regard to the striking morphologies they exhibit. To date, there are nearly 60 known binary central stars of PNe (bCSPNe). However, both theory and observation indicate that this figure represents only the t…

A compendium of distances to molecular clouds in the Star Formation Handbook
DOI: 10.1051/0004-6361/201936145 Bibcode: 2020A&A...633A..51Z

Alves, João; Speagle, Joshua S.; Zucker, Catherine +4 more

Accurate distances to local molecular clouds are critical for understanding the star and planet formation process, yet distance measurements are often obtained inhomogeneously on a cloud-by-cloud basis. We have recently developed a method that combines stellar photometric data with Gaia DR2 parallax measurements in a Bayesian framework to infer th…

The Spectrometer/Telescope for Imaging X-rays (STIX)
DOI: 10.1051/0004-6361/201937362 Bibcode: 2020A&A...642A..15K

Krucker, Säm; Veronig, A. M.; Rodríguez-Pacheco, J. +86 more


Aims: The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter is a hard X-ray imaging spectrometer, which covers the energy range from 4 to 150 keV. STIX observes hard X-ray bremsstrahlung emissions from solar flares and therefore provides diagnostics of the hottest (⪆10 MK) flare plasma while quantifying the location, spectrum,…

Hunting for open clusters in Gaia DR2: 582 new open clusters in the Galactic disc
DOI: 10.1051/0004-6361/201937386 Bibcode: 2020A&A...635A..45C

Castro-Ginard, A.; Jordi, C.; Luri, X. +8 more

Context. Open clusters are key targets for studies of Galaxy structure and evolution, and stellar physics. Since the Gaia data release 2 (DR2), the discovery of undetected clusters has shown that previous surveys were incomplete.
Aims: Our aim is to exploit the Big Data capabilities of machine learning to detect new open clusters in Gaia DR2,…
