The long-standing paradox of the linear polarization signal of the Na I D1 line was recently resolved by accounting for the atom's hyperfine structure and the detailed spectral structure of the incident radiation field. That modeling relied on the simplifying angle-averaged (AA) approximation for partial frequency redistribution (PRD) in scattering

We present a transit-timing variation (TTV) and planetary atmosphere analysis of the Neptune-mass planet HAT-P-26 b. We present a new set of 13 transit light curves from optical ground-based observations and combine them with light curves from the Wide Field Camera 3 on the Hubble Space Telescope, the Transiting Exoplanet Survey Satellite, and

We present the design of the objective lens for the DRAGO-2 optical system, a compact SWIR camera designed for the space environment. DRAGO-2 is the long-focal variant of the DRAGO (Demonstrator of Remote Analysis of Ground Observations) series, developed for the ALISIO-1 mission of the IACTEC-Space team at the Instituto de Astrofísica de Canarias

NGC 7293, the Helix nebula, represents one of the rare instances in which theoretical predictions of stellar evolution can be accurately tested against observations since the precise parallax distance and the velocity and proper motion of the star are well known. We present numerical simulations of the formation of the Helix PN that are fully

Minkowski's Object and `Death Star galaxy' are two of the famous cases of rare instances when a radio jet has been observed to directly hit a neighbouring galaxy. RAD12, the RAD@home citizen science discovery with GMRT being presented here, is not only a new system being added to nearly half a dozen rare cases known so far but also the first case

NEOROCKS (Near-Earth Object Rapid Observation, Characterization and Key Simulations) is an European project, funded by the Horizon 2020 UE program. Its aim is to increase our knowledge of the NEO physical characterization through observations and data dissemination. NEOROCKS is an international consortium, involving Italy, France, UK, Czech
