Automatic Classification of Spectra with IEF-SCNN
Universe, 2023 Telescopes such as the Large Sky Area Multi-Object Spectroscopic Telescope and the Sloan Digital Sky Survey have produced an extensive collection of spectra, challenging the feasibility of manual classification in terms of accuracy and efficiency.

All Spectral Type LAMOST Spectra Library (ATLAS)
The Astrophysical Journal Supplement Series, 2023 We present an empirical stellar spectra library, ATLAS, with resolution R ∼ 1800 and wavelength coverage from 3800–8700 Å. These spectra are homogeneously observed by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope and have been released in

Kepler Bonus: Light Curves of Kepler Background Sources
The Astronomical Journal, 2023 NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

TESS–Gaia Light Curve: A PSF-based TESS FFI Light-curve Product
The Astronomical Journal, 2023 The Transiting Exoplanet Survey Satellite (TESS) is continuing its second extended mission after 55 sectors of observations. TESS publishes full-frame images (FFIs) at a cadence of 1800, 600, or 200 s, allowing light curves to be extracted for stars ...
