During all stages of evolution, stars oscillate as a superposition of normal modes of certain frequencies that are indicative of their internal structures and compositions. These vibrations are visible as surface brightness fluctuations, and have been observed by numerous telescopes.

Event though there is no firm evidence for their presence to date, a considerable fraction of extrasolar planets are expected to host a magnetic field.

In the current JWST era, detailed observations of the first generation of galaxies have started to revolutionize our knowledge of the early Universe, with outstanding but also puzzling discoveries.

In this talk I focus on the analysis of two of ALMA-IMF Large program protoclusters, the G353.41 and the G351.77, located at a distance of ∼2 kpc and with masses ∼2.5×10^3 M⊙ within 2pc^2 , and both embedded in larger-scale (∼8 pc) "mother filaments".

I will talk about a recent study led by IAA-CSIC focused on the atmospheric H escape during high obliquity period in recent Mars (average ~35º in last millions of years).

Several models of nuclear dust in active galactic nuclei (AGN) have been presented in the literature to determine its physical and geometrical properties, usually assuming the dust density distribution as the main aspect producing differences in the mid-infrared (MIR) emission of AGNs.

The acceleration of the expansion rate of the Universe is yet to be explained. Several models, including LCDM, try to explain this acceleration. LCDM bases its explanation on a mysterious dark energy, adding up to ~75% of the total energy density of the Universe.

At the end of the 20th century, we thought we had a solid understanding of how low-mass stars evolved into planetary nebulae.

Quantum computing can solve specific problems much faster than classical computing concepts.

Star-Planet Interactions (SPIs) encompass a range of physical processes that occur in close-in exoplanetary systems, where the proximity between a star and its planet leads to complex magnetic, gravitational, and atmospheric effects.

The study of protoplanetary disks is essential for understanding stellar evolution and the origins of planets. However, these systems present significant observational challenges due to their small angular size, low surface brightness, and complex structure.

Calar Alto has a new tenant: PANIC, the PAnoramic Near-Infrared Camera for Calar Alto. PANIC is a project jointly developed by the MPIA in Heidelberg, Germany, and the IAA in Granada, Spain, for the Calar Alto Observatory (CAHA; Almería, Spain).

The WST project aims to design and construct an innovative 10-metre class wide-field spectroscopic survey telescope (WST) in the southern hemisphere.

The rapid deployment of satellite megaconstellations is fundamentally changing the sky, posing a growing challenge to both optical and radio astronomy.

The PARSEC project is a multiwavelength investigation of the centers of galaxies at parsec scales. In this presentation, I will provide a direct visualization of the star formation process in the centers of galaxies, resolved into their building blocks—the star clusters.

Nowadays, we are experiencing a revolution in astronomical surveys. Thanks to ground-based and orbiting telescopes, millions of observations of asteroids in various photometric filters are available.

The shallow potential wells of low-mass galaxies, commonly known as dwarf galaxies, make them highly susceptible to environmental effects, often leading to the complete cessation of star formation.

Triple star systems hold significant astrophysical importance, offering profound insights into stellar evolution, dynamical interactions, and mass transfer processes.

In this talk, I will present J-HERTz, the J-PLUS Heritage Exploration of Radio Targets at z < 5, a multi-wavelength catalog combining LoTSS DR2 radio data, WISE infrared detections, and J-PLUS DR3 optical narrow-band observations.

Cosmic dust particles are produced from the sublimation of comets and by collisions between asteroids.
