Seismic inference of 57 stars using full-length Kepler data sets [PDF]
EPJ Web of Conferences, 2017 We present stellar properties of 57 stars from a seismic inference using full-length data sets from Kepler (mass, age, radius, distances). These stars comprise active stars, planet-hosts, solar-analogs, and binary systems.

Stellar Population Properties in the Stellar Streams around SPRC047
The Astrophysical JournalWe have investigated the properties (e.g., age, metallicity) of the stellar populations of a ringlike tidal stellar stream (or streams) around the edge-on galaxy SPRC047 ( z = 0.031) using spectral energy distribution (SED) fits to ...

Properties of stellar activity cycles [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe current photometric datasets, that span decades, allow for studying long-term cycles on active stars. Complementary Ca H&K observations give information also on the cycles of normal solar-like stars, which have significantly smaller, and less easily detectable, spots.

Interaction Between Convection and Pulsation [PDF]
Living Reviews in Solar Physics, 2015 This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the

Stellar Ages: A Code to Infer Properties of Stellar Populations
The Astrophysical JournalWe present a novel statistical algorithm, Stellar Ages, which currently infers the age, metallicity, and extinction posterior distributions of stellar populations from their magnitudes.

Stellar mass as the ‘glocal’ driver of galaxies’ stellar population properties [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The properties of the stellar populations in a galaxy are known to correlate with the amount and the distribution of stellar mass. We take advantage of the maps of light-weighted mean stellar age $\mathit {\mathrm{ Age}_{\mathrm{ wr}}}$ and metallicity $\mathit {\mathrm{ Z}_{*\mathrm{ wr}}}$ for a sample of 362 galaxies from the

Astrophysical Properties of 600 Bona Fide Single Stars in the Hyades Open Cluster
The Astronomical Journal, 2023 The determination of the astrophysical properties of stars remains challenging and frequently relies on the application of stellar models. Stellar sequences in nearby open clusters provide some of the best means to test and calibrate stellar evolutionary

The True Nature of the Brightest Local Triple Stellar Candidates within 100 pc in the Galaxy
The Astronomical Journal, 2023 We present a study of a sample of bright ( V ≤ 10 mag) and close ( d ≤ 100 pc) triple–stellar system candidates in the galaxy, consisting of eight systems in total.
