En este trabajo se reinterpreta el heroon de El Pajarillo, en el marco del mito de la katabasis o viaje del héroe al inframundo. Para esta lectura se han realizado estudios arqueoastronómicos y se ha integrado el heroon en un camino de pagus, que sigue las aguas del río Jandulilla. En este nuevo territorio se ha añadido un nuevo hito arqueológico

V Sge is a peculiar, highly luminous long-period (12.34 h) binary star that can display a supersoft X-ray emitting component when in the faint phase of its $V \approx 10-13$ mag variability range. Apparently undergoing Eddington-limited accretion from its more massive secondary, it is in a very rare, short-lived evolutionary phase towards the

We report the discovery of a new black-widow millisecond pulsar, PSR J1544–2555, associated with the Fermi-Large Area Telescope (LAT) source 4FGL J1544.2–2554. Optical, radio, and gamma-ray observations confirmed its nature as a compact spider binary system. Optical photometry from ULTRACAM revealed a $\sim$2.7-h orbital period, guiding MeerKAT

The Gaia BP/RP spectra provide an excellent opportunity to search for extremely metal-poor (EMP; [M/H] ≤ –3.0) stars. In this study, we assess the potential of our Gaia BP/RP-based candidate catalog, vetting newly identified EMP candidates with higher-resolution follow-up observations. The candidates are selected based on the metallicity derived

Observations and high-resolution hydrodynamical simulations indicate that massive star clusters form through a complex hierarchical assembly. We use simulations including post-Newtonian dynamics (the BIFROST code) and stellar evolution (the SEVN module) to investigate this collisional assembly. With a full initial stellar mass function, we study

Long-period radio transients (LPTs) are periodic radio sources showing pulsed emission on time-scales from minutes to hours. The underlying sources behind this emission are currently unclear. There are two leading candidates: neutron stars or white dwarfs. Neutron stars could emit at LPT time-scales as magnetars, binaries, or precessing sources
