HiPERCAM is a quintuple-beam imager that saw first light on the 4.2 m William Herschel Telescope (WHT) in October 2017 and on the 10.4 m Gran Telescopio...
First measurements and upgrade plans of the MAGIC intensity interferometer
The two MAGIC 17-m diameter Imaging Atmospheric Cherenkov Telescopes have been equipped to work also as an intensity interferometer with a deadtime-free, 4...
First OB-stars in the iron-poor local group galaxy Sextans A
Massive stars are crucial to understand the chemical and dynamical evolution of the Universe. Our knowledge of their physics at sub-SMC metallicities, dominant...
First OB-stars in the iron-poor Local Group galaxy sextans A
The study of the early Universe relies on our ability to check our models by analyzing the behaviour of astrophysical objects at conditions close to those of...
First Observational Evidences for the Presence of Active, Localized Magnetic Structures in White Dwarfs
The magnetic white dwarf WD 1953-011 demonstrates the presence of two-component magnetic field geometry in photosphere. The geometry consists of a weak, large...
First Performance of the GOLF-NG Instrumental Prototype Observing the Sun in Tenerife
The primary challenge of Global Oscillations at Low Frequency New Generation (GOLF-NG) is the detection of the low-frequency solar gravity and acoustic modes...
First Release of PLATO Consortium Stellar Limb-darkening Coefficients
We release the first grid of stellar limb-darkening coefficients (LDCs) and intensity profiles (IPs) computed by the consortium of the PLAnetary Transits and...
