Context. The latest Gaia Focused Product Release (FPR) has provided variability information for ∼1000 long-period red giant binaries, including almost ∼700 ellipsoidal binary candidates, thus providing the largest sample to date of this binary type with both photometric and spectroscopic time series observations. Aims. We aim to characterize both

Radar observations of 2020 BX 12 conducted with the S-band planetary radar system (2380 MHz, 12.6 cm) at the Arecibo Observatory on 2020 February 4 and 5 revealed that this potentially hazardous asteroid is a binary system. Spectroscopic observations with the 10.4 m Gran Telescopio Canarias on 2024 February 16 indicate that 2020 BX 12 is an S

Massive stars drive the ionization and mechanical feedback within young star-forming regions. The Large Magellanic Cloud (LMC) is an ideal galaxy for studying individual massive stars and quantifying their feedback contribution to the environment. We analyze eight exemplary targets in LMC N11 B from the Hubble UV Legacy Library of Young Stars as

Context. Samples from the asteroid Ryugu provide key information on the initial composition and evolutionary processes of primitive bodies. Aims. This study aims to detect H 2O spectral features associated with inter-layer water in a statistically significant number of Ryugu grains protected from terrestrial contamination. Methods. We analysed

Ultra-hot Jupiters, an extreme class of planets not found in our Solar System, provide a unique window into atmospheric processes. The extreme temperature contrasts between their day and night sides pose a fundamental climate puzzle: how is energy distributed? To address this, we must observe the three-dimensional structure of these atmospheres

We present seeing-limited (0.8″) near-infrared integral field spectroscopy data of the type-2 quasars, QSO2s, SDSS J135646.10+102609.0 (J1356) and SDSS J143029.89+133912.1 (J1430, the Teacup), both belonging to the Quasar Feedback, QSOFEED, sample. The nuclear K-band spectra (1.95–2.45 μm) of these radio-quiet QSO2s reveal several H 2 emission
