Composition of super-Earths, super-Mercuries, and their host stars
V. Adibekyan, N. C. Santos, C. Dorn +11
Because of their common origin, it was assumed that the composition of planet building blocks should, to a first order, correlate with stellar atmospheric composition, especially f…
Detection of anomalous element distribution in the extremely slowly rotating magnetic O9.7 V star HD 54879
S. P. Järvinen, S. Hubrig., M. Schöller +4
The O9.7 V star HD 54879 is currently the only massive magnetic star whose magnetic field geometry and rotation period are not constrained. Over the last three years, we gathered a…
The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…
Thermal imaging of dust hiding the black hole in the Active Galaxy NGC 1068
Violeta Gamez Rosas, Jacob W. Isbell, Walter Jaffe +49
In the widely accepted 'Unified Model' solution of the classification puzzle of Active Galactic Nuclei, the orientation of a dusty accretion torus around the central black hole dom…
Galaxy populations in the Hydra I cluster from the VEGAS survey I. Optical properties of a large sample of dwarf galaxies
Antonio La Marca, Reynier Peletier, Enrichetta Iodice +17
At ~50 Mpc, the Hydra I cluster of galaxies is among the closest cluster in the z=0 Universe, and an ideal environment to study dwarf galaxy properties in a cluster environment. We…
New Periodograms Separating Orbital Radial Velocities and Spectral Shape Variation
Avraham Binnenfeld, Sahar Shahaf, Richard I. Anderson +1
We present new periodograms that are effective in distinguishing Doppler shift from spectral shape variability in astronomical spectra. These periodograms, building upon the concep…
The Massive and Distant Clusters of WISE Survey XI: Stellar Mass Fractions and Luminosity Functions of MaDCoWS Clusters at
Bandon Decker, Mark Brodwin, Ripon Saha +14
We present stellar mass fractions and composite luminosity functions (LFs) for a sample of \Ncl\ clusters from the Massive and Distant Clusters of WISE Survey (MaDCoWS) at a redshi…
The Pristine survey -- XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations
R. Lucchesi, C. Lardo, P. Jablonka +14
We present a one-dimensional, local thermodynamic equilibrium (1D-LTE) homogeneous analysis of 132 stars observed at high-resolution with ESPaDOnS. This represents the largest samp…
The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE
A. Chiavassa, K. Kravchenko, M. Montargès +50
Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…
p-winds: an open-source Python code to model planetary outflows and upper atmospheres
Leonardo A. Dos Santos, Aline A. Vidotto, Shreyas Vissapragada +6
Atmospheric escape is considered to be one of the main channels for evolution in sub-Jovian planets, particularly in their early lives. While there are several hypotheses proposed…
Brightest stars of irregular and low-massive spiral galaxies
Nickolay Tikhonov, Olga Galazutdinova, Gulnara Karataeva +4
A search for a correlation between the luminosities of the brightest stars and luminosities of their host galaxies was carried out on archived Hubble Space Telescope (HST) F606W or…
The post-common-envelope binary central star of the planetary nebula Ou 5: a doubly-eclipsing post-red-giant-branch system
David Jones, James Munday, Romano Corradi +10
We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou~5. Low-resolution spectra obtained duri…
NOEMA confirmation of an optically dark ALMA-AzTEC submillimetre galaxy at . A late-stage starburst prior to quenching
Soh Ikarashi, R. J. Ivison, William I. Cowley +1
We have obtained 1 and 3 mm spectral scans of ASXDF1100.053.1 using NOEMA. ASXDF1100.053.1 is an unlensed optically dark millimetre-bright SMG with (), which…
LoTSS Jellyfish Galaxies III. The first identification of jellyfish galaxies in the Perseus cluster
Ian D. Roberts, Reinout J. van Weeren, Roland Timmerman +4
In this paper we report the first identification of jellyfish galaxies in the Perseus cluster (Abell 426). We identified four jellyfish galaxies (LEDA 2191078, MCG +07-07-070, UGC…
ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
Laser guide star return-flux gain from frequency chirping
J. Hellemeier, M. Enderlein, M. Hager +7
Spectral hole burning reduces sodium laser guide star efficiency. Due to photon recoil, atoms that are initially resonant with the single-frequency laser get Doppler shifted out of…
