We used the HARPS-North high resolution spectrograph (ℛ = 115 000) at Telescopio Nazionale Galileo (TNG) to observe one transit of the highly irradiated planet MASCARA-2b/KELT-20b. Using only one transit observation, we are able to clearly resolve the spectral features of the atomic sodium (Na I) doublet and the Hα line in its atmosphere, which are

We present the updated version of the MOVIS-C catalog based on VISTA-VHS DR5 release. The near-infrared colors - (Y-J), (H-Ks), (J-Ks) are provided for 53 447 Solar System objects, thus being the largest set of spectro-photometric data in the near-infrared region. Taxonomic classification based on a probabilistic approach and machine-learning

Based on the stellar orbit distribution derived from orbit-superposition Schwarzschild models, we decompose each of 250 representative present-day galaxies into four orbital components: cold with strong rotation, warm with weak rotation, hot with dominant random motion, and counter-rotating (CR). We rebuild the surface brightness (Σ) of each

We present MOLPOP-CEP, a universal line transfer code that allows the exact calculation of multi-level line emission from a slab with variable physical conditions for any arbitrary atom or molecule for which atomic data exist. The code includes error control to achieve any desired level of accuracy, providing full confidence in its results

We investigated the infrared (IR) dust emission from PN IC 418, using a detailed model controlled by a previous determination of the stellar properties and the characteristics of the photoionized nebula, keeping as free parameters the dust types, amounts, and distributions relative to the distance of the central star. The model includes the ionized

Most of the V-types that are known are located in the inner main belt and are members of the Vesta collisional family. The analysis of the photometric and spectroscopic properties of asteroids inside and outside the Vesta family, including V-types in the middle and outer main belt, can answer questions about the existence of differentiated bodies
