Asteroid Ryugu was observed up close for almost a year and a half by the instruments on-board the Japanese Aerospace eXploration Agency (JAXA) Hayabusa2 spacecraft. It has been shown that in the near-infrared wavelength ranges, the asteroid exhibits relatively homogeneous spectral characteristics: including a very low reflectance factor, a slight

I will report on our recent discovery of a wide-spread photometric variability among hot (~20,000 – 30,000 K) extreme horizontal branch (EHB) stars in Galactic globular clusters. The EHB variability is periodic, displaying single-wave, low-amplitude and ~2-50 days modulations. The variability cannot be ascribed to either binary evolution or

We present a short update about the Spanish Fireball and Meteorite Recovery Network (in brief known as SPMN) after 25 years of continuous monitoring of the sky over Spain and bordering countries. A recent progress has been done in the development of a unique software called 3D-FireToc, which allows the detection and fully automatic reduction of

Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent opportunities for addressing the question of the evolution of exoplanetary systems directly after the RGB phase of evolution. Aims: In this project we aim to perform a transit survey in all

At the heart of the computation of model atmospheres there is the so-called Stellar Atmosphere Problem, which consists of the self-consistent solution of the radiative transfer equations under specific constraints. The amazing progresses achieved in the field since the 1970s are due to both the dramatic increase of the computational facilities and

Conventionally, galaxy morphological classifications are defined by visual assessment. However, visual classification systems such as Hubble types can be intrinsically biased due to the subjective judgement of human classifiers. Additionally, since morphological "classifications" into types is an important and complementary process, it is not clear
