Contact binaries consist of two strongly interacting component stars where they are filling
their critical Roche lobes and sharing a common envelope. Most of them are main-sequence …

Context. The astrophysical characterisation of sources is among the major new data
products in the third Gaia Data Release (DR3). In particular, there are stellar parameters for …

We derive and publish data-driven estimates of stellar metallicity [M/H] for∼ 175 million stars
with low-resolution XP spectra published in Gaia DR3. The [M/H] values, along with T eff and …

Context. The third Gaia data release (Gaia DR3) contains, beyond the astrometry and
photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra …

Abstract The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) general
survey is a spectroscopic survey that will eventually cover approximately half of the celestial …

We present the determination of stellar parameters and individual elemental abundances for
6 million stars from∼ 8 million low-resolution (R∼ 1800) spectra from LAMOST DR5. This is …

Abstract The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, also
called the Guo Shou Jing Telescope) is a special reflecting Schmidt telescope. LAMOST's …

Previous measurements of stellar properties for K2 stars in the Ecliptic Plane Input Catalog
largely relied on photometry and proper motion measurements, with some added …

EW-type eclipsing binaries (hereafter called EWs) are strong interacting systems in which
both component stars usually fill their critical Roche lobes and share a common envelope …

Abstract We introduce the Large Sky Area Multi-Object Fiber Spectroscopic Telescope
(LAMOST) stellar parameter pipeline at Peking University–lsp3, developed and …
