We present [C/Fe] and [N/Fe] abundance ratios and CH(λ4300) and S(λ3883) index measurements for 94 red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy from VLT/VIMOS MOS observations at a resolving power R = 1150 at 4020 Å. This is the first time that [N/Fe] abundances are derived for a large number of stars in a dwarf spheroidal

Using UV-to-H broad and narrow-band HST imaging, we derive the ages and masses of the 11 brightest star clusters in the dwarf galaxy NGC5253. This galaxy, located at ~3 Mpc, hosts an intense starburst, which includes a centrally-concentrated dusty region with strong thermal radio emission (the `radio nebula'). The HST imaging includes data from the

We present an analysis of seven spatially resolved planetary nebulae (PNe), NGC 2440, NGC 3242, NGC 5315, NGC 5882, NGC 7662, IC 2165, and IC 3568, from observations in the Cycle 19 program GO 12600 using HST STIS. These seven observations cover the wavelength range 1150-10,270 Å with 0.2 and 0.5 arcsec wide slits, and are co-spatial to within 0.1

The Slovak Video Meteor Network based on four stations from October 2013 (double station from 2009) and two cameras on the Canary Islands from March 2015 have recorded several tens of thousands meteors by the end of 2015. Naturally, only a part (about 20%) was observed simultaneously. Using precise all-sky astrometry (Borovička, 1995) and our own

We have recently identified a young, very red (J - Ks = 2.47 mag) late L-type companion at 8.06'' +/- 0.03'' (~102 AU) from a previously unrecognized M dwarf. We determined the parallactic distance of the system to be 12.7+/-1.0 pc. Non-detection of lithium and the kinematics of the primary allowed us to constrain the age of the system in the range

A search for the pair production of new light bosons, each decaying into a pair of muons, is performed with the CMS experiment at the LHC, using a dataset corresponding to an integrated luminosity of 20.7 fb-1 collected in proton-proton collisions at center-of-mass energy of √{ s} = 8 TeV. No excess is observed in the data relative to standard
