Context. Hot Jupiters are among the most suitable targets for atmospheric studies. Expanding the number of hot gaseous giant planets with atmospheric characterisations can improve our understanding of the chemical-physical properties of their atmospheres, as well as the formation and evolution of these extreme planets. Aims. In this work, we use

We present two cases of Lyα changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously at z > 2 through the Dark Energy Spectroscopic Instrument and the Sloan Digital Sky Survey. It is the first time to capture CL events in Lyα at high redshift, which is crucial for

The formation of low-mass stars is a complex and crucial process for understanding stellar evolution and planet formation. In the current scenario of low-mass star formation, after core collapse, the infalling material from the envelope is stored in the circumstellar disk. From this disk, the material reaches the forming star by following the star

The assembly of supermassive black hole (SMBH) mass (M •) and stellar mass (M *) in galaxies can be studied via the redshift evolution of the M •–M * relation, but the ways in which selection bias and physical assembly channels affect this evolution are uncertain. To address this, we compare the M •–M * relation for local massive (M * > 10 10.5 M ⊙

We present the discovery and characterization of TOI-4364b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground-based follow-up photometry. The planet orbits a bright M dwarf (K = 9.1 mag) at a distance of 44 pc, with an orbital period of 5.42 days and an equilibrium temperature of

The spectral diversity of trans-Neptunian objects (TNOs) is crucial for understanding the processes that led to the formation and evolution of planetesimals in the outer solar system. Using near-IR (NIR) spectra obtained by the James Webb Space Telescope (JWST) as part of the DiSCo-TNOs large program, we report the detection of well-clustered
