THE ALPINE-ALMA [C II] SURVEY. MOLECULAR GAS BUDGET IN THE EARLY UNIVERSE AS TRACED BY [C II]

Redazione
(AGENPARL) – GARCHING (GERMANY), mar 24 novembre 2020 First Author: Dessauges-Zavadsky, M.Instruments: ALMA_Band_7, ALMA_BandsProgramIDs: 2017.1.00428.LBibCode: 2020A&A…643A…5D The molecular gas content of normal galaxies at z > 4 is poorly constrained because the commonly used molecular gas tracers become hard to detect at these high redshifts. We use the [C II]......

THE NEAR-INFRARED COMPANION TO HD 94660 (=KQ VEL)

Redazione
(AGENPARL) – GARCHING (GERMANY), dom 22 novembre 2020 First Author: Scholler, M.Instruments: PIONIERProgramIDs: 0101.D-0399BibCode: 2020A&A…642A.188S Context. The Bp star HD 94660 is a single-lined spectroscopic binary. Some authors have suggested that the unseen companion of at least 2 M☉ may be a compact object. Aims: We intend to study this......

TOMOGRAPHY OF COOL GIANT AND SUPERGIANT STAR ATMOSPHERES. III. VALIDATION OF THE METHOD ON VLTI/AMBER OBSERVATIONS OF THE MIRA STAR S ORI

Redazione
(AGENPARL) – GARCHING (GERMANY), dom 22 novembre 2020 First Author: Kravchenko, KaterynaInstruments: AMBERProgramIDs: 084.D-0595BibCode: 2020A&A…642A.235K Context. Asymptotic giant branch (AGB) stars are characterized by substantial mass loss, however the mechanism behind it not yet fully understood. The knowledge of the structure and dynamics of AGB-star atmospheres is crucial to better......

SPATIALLY RESOLVING THE CHEMICAL COMPOSITION OF THE PLANET BUILDING BLOCKS

Redazione
(AGENPARL) – GARCHING (GERMANY), dom 22 novembre 2020 First Author: Matter, A.Instruments: MIDIProgramIDs: 090.C-0110BibCode: 2020MNRAS.497.2540M The inner regions of protoplanetary discs (from ∼0.1 to 10 au) are the expected birthplace of planets, especially telluric. In those high-temperature regions, solids can experience cyclical annealing, vapourisation, and recondensation. Hot and warm dusty......
