Fundamental Parameters of 87 Stars from the Navy Precision Optical Interferometer [PDF]
, 2017 We present the fundamental properties of 87 stars based on angular diameter measurements from the Navy Precision Optical Interferometer, 36 of which have not been measured previously using interferometry.

Fundamental parameters and infrared excesses of Tycho–Gaia stars [PDF]
, 2017 Effective temperatures and luminosities are calculated for 1,475,921 Tycho-2 and 107,145 Hipparcos stars, based on distances from Gaia Data Release 1. Parameters are derived by comparing multi-wavelength archival photometry to BT-Settl model atmospheres.

The Gaia–Kepler Stellar Properties Catalog. I. Homogeneous Fundamental Properties for 186,301 Kepler Stars [PDF]
Astronomical Journal, 2020 An accurate and precise Kepler Stellar Properties Catalog is essential for the interpretation of the Kepler exoplanet survey results. Previous Kepler Stellar Properties Catalogs have focused on reporting the best-available parameters for each star, but ...

The IGRINS YSO Survey. I. Stellar Parameters of Pre-main-sequence Stars in Taurus-Auriga [PDF]
Astrophysical Journal, 2021 We present fundamental parameters for 110 canonical K- and M-type (1.3−0.13 M ⊙) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous determination of effective temperature (T eff), surface gravity (log g), magnetic-field ...

Fundamental parameters of eight Am stars: comparing observations with theory [PDF]
, 2014 In this paper we present a detailed analysis of a sample of eight Am stars, four of them are in the Kepler field of view. We derive fundamental parameters for all observed stars, effective temperature, gravity, rotational and radial velocities, and ...
