Most current and planned near-Earth objects (NEO) surveys are made with ground-based telescopes and carried out in the visible wavelength range. However, this approach has some limitations, such as (1) weather dependency, (2) only a portion of the night sky is visible from any given location on Earth, (3) NEOs are difficult to detect at low

Context. The abundance discrepancy problem in planetary nebulae (PNe) has long puzzled astronomers. NGC 6153, with its high abundance discrepancy factor (ADF ~ 10), provides a unique opportunity to study the chemical structure and ionisation processes within these objects. Aims. We aim to understand the chemical structure and ionisation processes

The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands of main sequence solar-type and subgiant stars. This paper is the first of a series dedicated to the preparation of the analysis of stellar surface rotation and photospheric activity with

TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

The Mg II k resonance line is commonly used for diagnosing the solar chromosphere. We theoretically investigated its intensity and polarization in solar prominences, taking 3D radiative transfer and Hanle and Zeeman effects into account. We used an optically thick 3D model representative of a solar prominence and applied several inversion methods

Introduction Hera is ESA's first planetary defense mission designed to characterize the binary near-Earth asteroid (65803) Didymos [1]. Its secondary component, Dimorphos, was the target of the large-scale controlled collision with the NASA/DART spacecraft in September 2022 [2]. Thus, the Hera mission will provide an unprecedented opportunity to
