Revisiting the Hubble sequence in the SDSS DR7 spectroscopic sample: a publicly available Bayesian automated classification
We present an automated morphological classification in 4 types (E, S0, Sab, Scd) of ~700 000 galaxies from the SDSS DR7 spectroscopic sample based on support...
SDSS-IV MaStar: A Large and Comprehensive Empirical Stellar Spectral Library—First Release
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength...
Single stellar populations in the near-infrared. I. Preparation of the IRTF spectral stellar library
We present a detailed study of the stars of the NASA InfraRed Telescope Facility (IRTF) spectral library to understand its full extent and reliability for use...
Size and albedo distributions of asteroids in cometary orbits using WISE data
Context. Determining whether asteroids in cometary orbits (ACOs) are dormant or extinct comets is relevant for understanding the end-states of comets and the...
Spectroscopic Madness - The ProAm WR 140 campaign in 2009/10
Golden Age of Astronomy” does not only influence professional but also amateur astronomy. Today, amateurs basically use the same technologies as the...
SpectroTranslator: Deep-neural network algorithm for homogenising spectroscopic parameters
Context. In modern Galactic astronomy, stellar spectroscopy plays a pivotal role in complementing large photometric and astrometric surveys and enabling deeper...
Context. The CoRoT mission was the first dedicated to the search for exoplanets from space. The CoRoT exoplanet channel observed about 163 600 targets to detect...
Surface Rotation and Photometric Activity for Kepler Targets. II. G and F Main-sequence Stars and Cool Subgiant Stars
Dark magnetic spots crossing the stellar disk lead to quasiperiodic brightness variations, which allow us to constrain stellar surface rotation and photometric...
