The third science flight of the balloon-borne solar observatory SUNRISE carries three entirely new post-focus science instruments with spectropolarimetric capabilities, concurrently covering an extended spectral range from the near ultraviolet to the near infrared. Sampling a larger height range, from the low photosphere to the chromosphere, with

We present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from Optical Gravitational Lensing Experiment (OGLE), and giant stars from APOGEE and Gaia that have distances placing them in the inner Galaxy. First, using a sample of 1879 ab-type RR Lyrae stars (RRabs) from OGLE-IV, we

AM CVn systems are a subclass of cataclysmic variables where two DB WDs exchange H-depleted material under short period orbits -in the range approx. 5 - 65 minutes. The prototype, AM CVn (=HZ9) itself, was first discovered in 1957 as a "peculiar" DB WD by Greenstein & Matthews and in 1967 Smak found its characteristic 17-18 min photometric

In this work we made use of the lists of candidate members obtained by Gutiérrez Albarrán et al. (2024) for a target sample of 42 open clusters, ranging from 1 Myr to 5 Gyr and observed within the Gaia-ESO survey (GES), with the aim of studying Li as an age indicator and deriving an empirical Li-age relation for FGK late-type stars. We conducted a

Many detected planets experience hydrodynamic atmospheric escape during some stage of their life. Most of those exoplanets are hot Jupiters and sub-Neptunes orbiting close to their stars. Traditionally, the escape in these evaporating planets has been studied by Lyman-α line absorption measurements taken by instruments from space. Very recently, a

Galaxy quenching, the intricate process through which galaxies transition from active star-forming states to retired ones, remains a complex phenomenon that requires further investigation. This study investigates the role of active galactic nuclei (AGNs) in regulating star formation by analyzing a sample of 643 nearby galaxies with redshifts
