Filter Results
  • Investigation of mass loss mechanism of LPVs

    In order to investigate the relations between the mass loss from pulsating red giants and quantities which can be obtained from observations, we have explored the behavior of...
  • Rotating models of A and F stars

    Magnitude differences between rotating and non-rotating copartners for a grid of models with solar metallicity are tabulated here. The results are expressed in terms of the...
  • Limb-darkening coefficients for ubvyUBVRIJHK

    Linear and non-linear limb-darkening coefficients for the photometric bands u v b y U B V R I J H K are computed for very low effective temperatures stars. The atmosphere models...
  • Chromospheric models of dwarf M stars

    Tables 4 and 5 give the atmospheric parameters for our models of dM stars Gl 588 and Gl 628. The columns give the column mass in g/cm^-2^, the electron temperature in K, the...
  • Miras temperatures, distances & magnitudes

    Effective temperatures are determined for a sample of 165 oxygen-rich Miras using indices related to molecular band strength of titanium oxide and vanadium oxide. Using a...
  • Model atmospheres for Vega

    (no description available)
  • Synthetic photometry of RR Lyr

    The luminosities and effective temperatures, as well as the whole bolometric light curves of non-linear convective RR Lyrae models with 0.0001<=Z<=0.006, are transformed...
  • Models for Intermediate-Mass Eclipsing Binaries

    We use estimates of ages and abundances made for a set of eclipsing binaries (Kovaleva, 2001, Cat. <J/AZh/78/1104), to re-calculate observational values of radii, effective...
  • Contact binaries from CSS DR2

    With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released. Deriving parameters for...
  • Periodic variable stars from LAMOST DR9

    Identifying and classifying variable stars is essential to time-domain astronomy. The Large Area Multi-Object Fiber Optic Spectroscopic Telescope (LAMOST) acquired a large...
  • 25 hot-Jupiter properties from HST & Spitzer

    Population studies of exoplanets are key to unlocking their statistical properties. So far, the inferred properties have been mostly limited to planetary, orbital, and stellar...
  • Predicted redshifts for 4FGL gamma-ray loud AGNs

    Measuring the redshift of active galactic nuclei (AGNs) requires the use of time-consuming and expensive spectroscopic analysis. However, obtaining redshift measurements of AGNs...
  • LAMOST variable sources based on ZTF phot.

    The identification and analysis of different variable sources is a hot topic in astrophysical research. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)...
  • Simulated exoplanets from TESS list of targets

    The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small planets orbiting stars bright enough for mass determination via ground-based radial velocity...
  • Solar wind 3D magnetohydrodynamic simulation

    We use a three-dimensional magnetohydrodynamic simulation of the solar wind to calculate cosmic-ray diffusion coefficients throughout the inner heliosphere (2R_{sun}_-3au). The...
  • redMaPPer cluster catalog from DES data

    We describe updates to the redMaPPer algorithm, a photometric red-sequence cluster finder specifically designed for large photometric surveys. The updated algorithm is applied...
  • Rosseland opacities with the OPAS model

    The OPAS opacity model has been used to calculate the radiative opacity of stellar plasmas in local thermodynamic equilibrium. According to the recent chemical composition...
  • Hydrogen and Helium EOS in brown dwarfs

    We present new equations of state (EOSs) for hydrogen and helium covering a wide range of temperatures from 60K to 10^7^K and densities from 10^-10^g/cm^3^ to 10^3^g/cm^3^. They...
  • Refractive indices of grain materials

    As small solid grains grow into larger ones in protoplanetary nebulae, or in the cloudy atmospheres of exoplanets, they generally form porous aggregates rather than solid...
  • Relativistic EOS for core-collapse SN simulations

    We construct the equation of state (EOS) of dense matter covering a wide range of temperature, proton fraction, and density for the use of core-collapse supernova simulations....
