Rotation and lithium depletion of M35 dwarfs
New fibre spectroscopy and radial velocities from the WIYN telescope are used to measure photospheric lithium in 242 high-probability, zero-age main-sequence F- to K-type... -
Redshifts and fluxes for emission-line galaxies
The forthcoming Dark Energy Spectroscopic Instrument (DESI) experiment plans to measure the effects of dark energy on the expansion of the Universe and create a 3D map of the... -
CCD Washington photometry of Antlia cluster
We present an extension of our previous research on the early-type galaxy population of the Antlia cluster (d~35Mpc), achieving a total coverage of ~2.6deg^2^ and performing... -
Magnetic activity based on LAMOST and Kepler
Stellar magnetic activity is an interesting phenomenon in late-type stars. We use the medium-resolution spectroscopic observations of 406069 late-type stars from LAMOST to... -
Study of NGC 381, NGC 2360 and Berkeley 68
We present UBVR_c_I_c_ photometric study of three intermediate age open star clusters NGC381, NGC2360, and Berkeley68 (Be68). We examine the cluster membership of stars using... -
MEGARA-GTC stellar spectral library I
MEGARA (Multi Espectrografo en GTC de Alta Resolucion para Astronomia) is an optical (3650-9750{AA}), fibre-fed, medium-high spectral resolution (R=6000, 12000 and 20000)... -
Faint radio source population at 15.7GHz - IV
We present 15-GHz Karl G. Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7GHz from the Tenth Cambridge (10C) survey. 67 out of the 95... -
Faint Standards for UKIDSS and VISTA ZYJHK
The currently defined 'United Kingdom Infrared Telescope (UKIRT) Faint Standards' have JHK magnitudes between 10 and 15, with K_median_=11.2. These stars will be too bright for... -
SN 2016gsd: an unusually luminous supernova
We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V=-19.95+/-0.08, this object is one of the brightest Type II... -
Nebular spectra of 111 Type Ia supernovae
We place statistical constraints on Type Ia supernova (SN Ia) progenitors using 227 nebular-phase spectra of 111 SNe Ia. We find no evidence of stripped companion emission in... -
Photometry and spectroscopy of RN LMC 1968
We present a comprehensive review of all observations of the eclipsing recurrent Nova LMC 1968 in the Large Magellanic Cloud which was previously observed in eruption in 1968,... -
Globular clusters in NGC 5907's stellar stream
We study the globular clusters (GCs) in the spiral galaxy NGC 5907 well-known for its spectacular stellar stream - to better understand its origin. Using wide-field... -
The SDSS extended PSFs
A robust and extended characterization of the Point Spread Function (PSF) is crucial to extract the photometric information produced by deep imaging surveys. Here we present the... -
Extremely metal-poor stars in SkyMapper DR1.1
We present and discuss the results of a search for extremely metal-poor stars based on photometry from data release DR1.1 of the SkyMapper imaging survey of the southern sky. In... -
Origin of stellar flares on M dwarfs using TESS
Detailed studies of the Sun have shown that sunspots and solar flares are closely correlated. Photometric data from Kepler/K2 has allowed similar studies to be carried out on... -
Young star clusters 2nd Galactic quadrant
Galactic spiral arms are traced using young objects as giant molecular clouds, HII regions, OB stars, or young open/embedded clusters. To improve the knowledge of the Galactic... -
BVRI photometry of the Type II-P SN 2017eaw
Broadband BVRI light curves of SN 2017eaw in NGC 6946 reveal the classic elements of a Type II-P supernova. The observations were begun on 16 May 2017 (UT), approximately 1 d... -
Variable stars in NGC 2244
We present results of the UBVIc variability search for variable stars in the young open cluster NGC 2244. In total, we found 245 variable stars. Most of them, are pre-main... -
Light curves of WASP-74
We present broad-band photometry of 11 planetary transits of the hot Jupiter WASP-74 b, using three medium-class telescopes and employing the telescope-defocusing technique.... -
UBVRI photometry in 48 globular clusters
We present wide-field, ground-based Johnson-Cousins UBVRI photometry for 48 Galactic globular clusters based on almost 90000 public and proprietary images. The photometry is...
