Evidence for elemental diffusion in the eclipsing binary star AI Phoenicis
Pierre F. L. Maxted, Nicholas Storm, Andreas J. Korn +7
AI Phe is an eclipsing binary star with an orbital period of 24.6 days for which the surface gravity and effective temperature are known from direct measurements to very high preci…
A closer look at the extended edge-on low-surface brightness galaxies
Anna S. Saburova, Damir Gasymov, Evgenii V. Rubtsov +13
To understand the origin of extended disks of low-surface brightness (LSB) galaxies, we studied in detail 4 such systems with large disks seen edge-on. Two of them are edge-on gian…
\HI{} 21cm observations and dynamical modelling of the thinnest galaxy: FGC 2366
K. Aditya, Arunima Banerjee, Peter Kamphuis +3
Superthin galaxies are bulgeless low surface brightness galaxies with unusually high major-to-minor axes ratio of the stellar disc, i.e.,. We present Giant Metrewave Rad…
New Generation Stellar Spectral Libraries in the Optical and Near-Infrared I: The Recalibrated UVES-POP Library for Stellar Population Synthesis
Sviatoslav Borisov, Igor Chilingarian, Evgenii Rubtsov +8
We present re-processed flux calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025 nm, which can be used for stellar population synthes…
RCSEDv2: homogenization of multi-wavelength photometric data
Victoria Toptun, Igor Chilingarian, Ivan Katkov +6
RCSEDv2 (https://rcsed2.voxastro.org/), the second Reference Catalog of Spectral Energy Distributions of galaxies includes the largest homogeneously processed photometric dataset f…
RCSEDv2: Open-source web tools for visualization of imaging and spectral data
Vladislav Klochkov, Ivan Katkov, Igor Chilingarian +6
We present a set of open-source web tools for visualization of spectral and imaging data, which we use in the second Reference Catalogue of Spectral Energy Distributions of galaxie…
RCSEDv2: the largest database of galaxy properties from a homogeneously processed multi-wavelength dataset
Igor Chilingarian, Sviatoslav Borisov, Vladimir Goradzhanov +6
The Reference Catalog of Spectral Energy Distributions of 800,000 galaxies (RCSED) includes the results of uniform re-processing of 800,000 SDSS DR7 galaxies at redshifts $0.007<z<…
RCSEDv2: Processing and analysis of 4+ million galaxy spectra
Vladimir Goradzhanov, Igor Chilingarian, Evgenii Rubtsov +6
RCSEDv2 (https://rcsed2.voxastro.org/), the second Reference Catalog of Spectral Energy Distributions of galaxies, provides the largest homogeneously analyzed collection of optical…
RCSEDv2: analytic approximations of k-corrections for galaxies out to redshift
Anastasia Kasparova, Igor Chilingarian, Sviatoslav Borisov +6
To compare photometric properties of galaxies at different redshifts, we need to correct fluxes for the change of effective rest-frame wavelengths of filter bandpasses, called -…
Hybrid minimization algorithm for computationally expensive multi-dimensional fitting
Evgenii Rubtsov, Igor Chilingarian, Ivan Katkov +3
Multi-dimensional optimization is widely used in virtually all areas of modern astrophysics. However, it is often too computationally expensive to evaluate a model on-the-fly. Typi…
Multi-segment and Echelle stellar spectra processing issues and how to solve them
Sviatoslav Borisov, Igor Chilingarian, Evgenii Rubtsov +7
High-quality stellar spectra are in great demand now - they are the most important ingredient in the stellar population synthesis to study galaxies and star clusters. Here we descr…
HI 21 cm observation and mass models of the extremely thin galaxy FGC 1440
K. Aditya, Peter Kamphuis, Arunima Banerjee +4
We present observations and models of the kinematics and distribution of neutral hydrogen (HI) in the superthin galaxy FGC 1440 with an optical axial ratio . Using the…
Lithium depletion and angular momentum transport in F-type and G-type stars in Galactic open clusters
Thibaut Dumont, Corinne Charbonnel, Ana Palacios +1
Open clusters provide clues to understand the evolution of Li7 at the surface of low-mass stars and its possible correlation with stellar rotation, which is a challenge for both st…
