The ALPINE-ALMA [C II] survey. Luminosity function of serendipitous [C II] line emitters at z ∼ 5
Hathi, Nimish P.; Koekemoer, Anton M.; Jones, Gareth C. +33 more
We present the first [C II] 158 µm luminosity function (LF) at z ∼ 5 from a sample of serendipitous lines detected in the ALMA Large Program to INvestigate [C II] at Early times (ALPINE). A study of the 118 ALPINE pointings revealed several serendipitous lines. Based on their fidelity, we selected 14 lines for the final catalog. According to…
Multiscale, multiwavelength extraction of sources and filaments using separation of the structural components: getsf
Men'shchikov, A.
High-quality astronomical images delivered by modern ground-based and space observatories demand adequate, reliable software for their analysis and accurate extraction of sources, filaments, and other structures, containing massive amounts of detailed information about the complex physical processes in space. The multiwavelength observations with …
The CALYPSO IRAM-PdBI survey of jets from Class 0 protostars. Exploring whether jets are ubiquitous in young stars
Maret, S.; Podio, L.; Codella, C. +10 more
Aims: As a part of the CALYPSO Large Program, we aim to constrain the properties of protostellar jets and outflows by searching for corresponding emission in a sample of 21 Class 0 protostars covering a broad range of internal luminosities (Lint from 0.035 L⊙ to 47 L⊙).
Methods: We analyzed high angular (…
Flares in open clusters with K2. II. Pleiades, Hyades, Praesepe, Ruprecht 147, and M 67
Kristiansen, Martti H.; Omohundro, Mark; Davenport, James R. A. +3 more
Context. Magnetic fields are a key component in the main sequence evolution of low mass stars. Flares, energetic eruptions on the surfaces of stars, are an unmistakable manifestation of magnetically driven emission. The occurrence rates and energy distributions of flares trace stellar characteristics such as mass and age. However, before flares ca…
Measuring the ratio of the gas and dust emission radii of protoplanetary disks in the Lupus star-forming region
de Gregorio-Monsalvo, I.; Pascucci, I.; Testi, L. +15 more
We performed a comprehensive demographic study of the CO extent relative to dust of the disk population in the Lupus clouds in order to find indications of dust evolution and possible correlations with other disk properties. We increased the number of disks of the region with measured RCO and Rdust from observations with the …
Perturbers: SPHERE detection limits to planetary-mass companions in protoplanetary disks
Ménard, F.; Garufi, A.; Henning, Th. +25 more
The detection of a wide range of substructures such as rings, cavities, and spirals has become a common outcome of high spatial resolution imaging of protoplanetary disks, both in the near-infrared scattered light and in the thermal millimetre continuum emission. The most frequent interpretation of their origin is the presence of planetary-mass co…
Solar Orbiter: Mission and spacecraft design
Müller, D.; Zouganelis, I.; Cipriani, F. +37 more
The main scientific goal of Solar Orbiter is to address the central question of heliophysics: `how does the Sun create and control the heliosphere?' To achieve this goal, the spacecraft carries a unique combination of ten scientific instruments (six remote-sensing instruments and four in-situ instruments) towards the innermost regions of the Solar…
A new, Gaia-based, catalogue of blue straggler stars in open clusters
Carraro, G.; Ahumada, J. A.; Rain, M. J.
Context. Blue straggler stars are exotic objects present in all stellar environments whose nature and formation channels are still partially unclear. They seem to be particularly abundant in open clusters (OCs), thus offering a unique chance to tackle these problems statistically.
Aims: We aim to build up a new and homogeneous catalogue of bl…
Mapping luminous hot stars in the Galaxy
Rix, H. -W.; Drimmel, R.; Poggio, E. +4 more
Luminous hot stars (MKs ≲ 0 mag and Teff ≳ 8000 K) dominate the stellar energy input to the interstellar medium throughout cosmological time, are used as laboratories to test theories of stellar evolution and multiplicity, and serve as luminous tracers of star formation in the Milky Way and other galaxies. Massive …
The first widespread solar energetic particle event observed by Solar Orbiter on 2020 November 29
Kulkarni, S. R.; Lario, D.; Laitinen, T. +66 more
Context. On 2020 November 29, the first widespread solar energetic particle (SEP) event of solar cycle 25 was observed at four widely separated locations in the inner (≲1 AU) heliosphere. Relativistic electrons as well as protons with energies > 50 MeV were observed by Solar Orbiter (SolO), Parker Solar Probe, the Solar Terrestrial Relations Ob…
