Abstract In the third APOKASC catalog, we present data for complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used 10 independent asteroseismic analysis techniques anchor our system on fundamental radii derived from Gaia L T eff . provide evolutionary state, surface gravity, mass, radius, age, to derive them 12,418 stars. This includes 10,036 exceptionally precise measurements, median fractional uncertainties in <mml:math...
Abstract The goal of the Open Cluster Chemical Abundances and Mapping (OCCAM) survey is to constrain key Galactic dynamic chemical evolution parameters by construction analysis a large, comprehensive, uniform data set infrared spectra for stars in hundreds open clusters. This sixth contribution from OCCAM presents SDSS/APOGEE Data Release 17 (DR17) results sample 150 clusters, 94 which we designate be “high-quality” based on appearance their color–magnitude diagram. We find APOGEE...
Large scale surveys open the possibility to investigate Galactic evolution both chemically and kinematically, however, reliable stellar ages remain a major challenge. Detailed chemical information provided by high-resolution spectroscopic of stars in clusters can be used as means calibrate recently developed tools for age-dating field stars. Using data from Open Cluster Abundances Mapping (OCCAM) survey, based on SDSS/APOGEE-2 we derive new empirical relationship between cluster...
We introduce a new binary detection technique, Binary INformation from Open Clusters using SEDs (binocs), which we show is able to determine reliable stellar multiplicity and masses over much larger mass range than current approaches. This technique determines accurate component of single systems the open clusters main sequence by comparing observed magnitudes multiple photometric filters synthetic star spectral energy distributions (SEDs) allowing systematically probing population for low...
In the third APOKASC catalog, we present data for complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used ten independent asteroseismic analysis techniques anchor our system on fundamental radii derived from Gaia $L$ $T_{\rm eff}$. provide evolutionary state, surface gravity, mass, radius, age, measurements to derive them 12,418 stars. This includes 10,036 exceptionally precise measurements, median fractional uncertainties in \nmax,...
