IntroductionThe observation of NEOs allows us to study the physical characteristics of the smallest size bodies of our Solar System as well as to impose constraints on their origin and evolution. Considering that these objects are in unstable orbits over the age of the Solar System, this implies that it is a transient population, which can be

IntroductionAsteroids lightcurves have been used extensively to derive many important physical characteristics such as rotational properties (rotational period and pole direction) and shape (Kaasalainen et al., 2004; Hanus et al., 2011; Durech et al., 2015), as well as to identify and characterize binary asteroids (Pravec et al., 2006). In addition

IntroductionThe asteroid (4660) Nereus is considered one of the most accessible targets for a rendez-vous space mission. It was proposed as a possible target for the NASA Near-Earth Asteroid Rendezvous (NEAR) and for JAXA Hayabusa spacecraft. The lightcurve analysis and the radar shape modeling revealed a long rotational period of ≅ 15.16 ± 0.04 h

Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system due to brightenings on a time-scale of a year. Gaia20bwa brightened by about half a magnitude, whereas Gaia20fgx brightened by about two and half magnitudes. We analysed

With the increasing size of the ground based telescopes, the lines used to carry and distribute cryogenic gas or fluid to instruments need continuously to be longer. Cryogenic transfer lines of a few 10 meters will be common in future infrastructures. Transfer cryogenic fluid requires highly insulated lines in order to minimise the coolant

We will present the opportunities of an ERASMUS+ strategic partnership KA2 funding schemes which we used to support (not only) early career researchers in astronomy. ERASMUS+ is a general funding scheme and we describe here one particular project funding education and international partnerhsip of institutions in astronomical research. Our first
