Calibration sample UBV and GALEX photometry
We derive transformation equations between GALEX and UBV colours by using the reliable data of 556 stars. We present two sets of equations: as a function of (only) luminosity... -
MALT90 Catalogue
The Millimetre Astronomy Legacy Team 90GHz survey aims to characterise the physical and chemical evolution of high-mass clumps. Recently completed, it mapped 90GHz line emission... -
WASP-127 b LCs, WASP-96 b transmission spectra
We present TransitFit, a package designed to fit exoplanetary transit light-curves. TransitFit offers multi-epoch, multi-wavelength fitting of multi-telescope transit data.... -
Solar activity components intensity profiles
The detection of Earth-like planets with the radial-velocity method is currently limited by the presence of stellar activity signatures. On rotational timescales, spots and... -
HST/COS UV spectroscopic survey of white dwarfs I
White dwarf studies carry significant implications across multiple fields of astrophysics, including exoplanets, supernova explosions, and cosmological investigations. Thus,... -
Star-forming complex S254-S258 HII regions
The S254-258 star-forming complex is a place of massive star formation where five OB-stars have created HII regions, visible as optical nebulae, and disrupted the parental... -
Stable accretion of EX Lup and TW Hya
We examine the long-term spectroscopic and photometric variability of EX Lupi and TW Hya, studying the presence of stable accretion and the role it plays in the observed... -
RASS-MCMF catalog
We present the RASS-MCMF catalogue of 8449 X-ray selected galaxy clusters over 25000deg^2^ of extragalactic sky. The accumulation of deep multiband optical imaging data, the... -
4 A-type stars abundances and spectra
We present chemical composition and fundamental parameters (the effective temperature, surface gravity and radius) for four sharp-lined A-type stars gamma Gem (HD 41705),... -
Properties of IC 4665 members
IC 4665 is one of only a dozen young open clusters with a 'lithium depletion boundary' (LDB) age. Using an astrometrically and spectroscopically filtered sample of cluster... -
NIR spectral atlas of early-type galaxies
We present a near infrared spectroscopic atlas of nearby, bright early-type galaxies with radio emission, containing 163 galaxies observed by the Palomar 200" TripleSpec... -
Optical spectra of M dwarfs blue depression
A blue depression is found in the spectra of M dwarfs from 4000 to 4500{AA}. This depression shows an increase toward lower temperatures though is particularly sensitive to... -
HATS-46 b EFOSC2 light curve
We have performed low-resolution ground-based spectroscopy of HATS-46 b in transmission, using the EFOSC2 instrument on the ESO New Technology Telescope (NTT). HATS-46 b is a... -
Reduced proper motion with Gaia DR3
With the advent of the European Space Agency's Gaia mission and its recent data releases EDR3 and DR3, the astronomy community has obtained the largest-ever cartograph of our... -
HII-CHI-Mistry-UV for AGN. Abundances
We present an adapted version of the code HII-CHI-mistry-UV (Perez-Montero & Amorin, 2017MNRAS.467.1287P) to derive chemical abundances from emission lines in the... -
The PHANGS-MUSE nebular catalogue
Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM). Their bright emission lines enable the measurement of physical properties, such... -
Millimeter-wave spectrum of 2-propanimine
Up to date, only six imines have been detected in the interstellar medium. The 3-carbon imine, 2-propanimine ((CH_3_)_2_C=NH), is predicted to be the structural isomer with the... -
Pristine survey. XX.
Ultra metal-poor stars ([Fe/H]<-4.0) are very rare, and finding them is a challenging task. Both narrow-band photometry and low-resolution spectroscopy have been useful tools... -
Ha-excess sources spectroscopic follow-up
State-of-the-art techniques to identify Ha emission line sources in narrow- band photometric surveys consist of searching for Ha excess with reference to nearby objects in the... -
HST photometry of NGC 1850
Young star clusters enable us to study the effects of stellar rotation on an ensemble of stars of the same age and across a wide range in stellar mass and are therefore ideal...
