Size Scaling of Clump Instabilities in Turbulent, Feedback-regulated Disks
Glazebrook, Karl; Fisher, Deanne B.; Obreschkow, Danail +5 more
We explore the scaling between the size of star-forming clumps and rotational support in massively star-forming galactic disks. The analysis relies on simulations of a clumpy galaxy at z = 2 and the observed DYnamics of Newly Assembled Massive Objects (DYNAMO) sample of rare clumpy analogs at z ≈ 0.1 to test a predictive clump size scaling propose…
Silicate features in the circumstellar envelopes of the Class I binary driving source of HH 250
Comerón, F.; Merín, B.; Reipurth, B. +1 more
Context. The silicate feature near 10 µm is one of the main tools available to study the mineralogy of circumstellar disks and envelopes, providing information on the thermal processing, growth, location, and circulation of dust grains.
Aims: We investigate the silicate feature of the two Class I components of HH 250-IRS, a resolved bin…
Publisher Correction: Martian dust storm impact on atmospheric H2O and D/H observed by ExoMars Trace Gas Orbiter
Montmessin, Franck; Belyaev, Denis A.; Fedorova, Anna A. +65 more
The surname of author Cathy Quantin-Nataf was misspelled `Quantin-Nata' , authors Ehouarn Millour and Roland Young were missing from the ACS Science Team list, and minor changes have been made to the author and affiliation lists; see accompanying Amendment. These errors have been corrected online.
Catalogue of Visual Binaries in Gaia DR2
Kovaleva, D. A.; Sapozhnikov, S. A.; Malkov, O. Y.
We use Gaia DR2 data to construct a catalogue of visual binaries between 10 pc and 100 pc distance from the Sun. Based on data on positions and parallaxes, we have compiled a list of binary candidates containing all pairs of stars positioned within 1 parsec to one another. We have developed an algorithm involving the separation of sky into smaller…

Investigation of the Effect of a Longitudinal Magnetic Field Component on the Dynamics of Protons inside a Plasmoid
Malova, H. V.; Malykhin, A. Yu.; Grigorenko, E. E.
Kinetic effects of the dynamics of protons in plasmoids with a non-zero longitudinal ( By) magnetic field component in a current sheet (CS) of a geomagnetic tail are considered. The results of modeling proton dynamics and a description of the mechanism of emergence of "north-south" density asymmetry are presented. The mechanism that is possibly re…
A new sample of southern radio galaxies: host-galaxy masses and star-formation rates
Jarvis, Matt J.; Prescott, Matthew; Marubini, Takalani +3 more
In this study we define a new sample of distant powerful radio galaxies in order to study their host galaxy properties and provide targets for future observations of H I absorption with new radio telescopes and to understand the fuelling and feedback from such sources. We have cross-matched the Sydney University Molonglo Sky Survey (SUMSS) radio c…
Investigating the OB associations in CMa using eclipsing binary systems: Preliminary results on LV CMa
Bakış, V.; Tunç, E.
In this study, an eclipsing binary of a short orbital period (P = 1.d1834857) LV CMa (V = 8.m7) is selected as a candidate member of an association in the direction of CMa OB1/R1 region. Light curves in UBVRcIc photometric bands were obtained and low-resolution (R ∼ 5500) spectra were collected. Prelimin…
The tricky line of sight towards Cygnus-X: The [DB2001] CL05 embedded cluster as a pilot case
Jiménez-Bailón, E.; Alves, J.; de la Fuente, D. +2 more
The nearest massive star-forming complex, Cygnus-X, is widely used as a laboratory for star cluster formation and feedback processes, under the implicit assumption that all its components are located roughly at the same distance. We present a multi-wavelength study of a 15' × 15' field in southern Cygnus-X, where different components involving clu…
On the Fon Astroplate Project Accomplishment
Ehgamberdiev, Sh. A.; Andruk, V. M.; Pakuliak, L. K. +10 more
The plan of the photographic survey of the northern sky (FON) was proposed in 1976 in Golosiiv observatory (now MAO NAS of Ukraine) by I. Kolchinsky and A. Onegina. The final project of the Compiled FONAC catalog (FON Astrographic Catalog) is based on the digital data of photographic plates exposed at four observatories. They are MAO NAS of Ukrain…
