Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red giant stars and to measure their global seismic constraints, which can be used to infer global stellar properties (e.g. masses, radii, and evolutionary states). Combining such precise constraints with photospheric abundances

The large- and small-scale environments around optically-selected AGN host galaxies and a control sample of non-active galaxies in the MaNGA survey have been investigated in order to evaluate the importance of the environment in AGN triggering. Using the MaNGA integral field spectroscopy, we quantify non-circular motions of the ionized gas and

The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a

We use the new QUIJOTE-MFI wide survey (11, 13, 17, and 19 GHz) to produce spectral energy distributions (SEDs), on an angular scale of 1°, of the supernova remnants (SNRs) CTB 80, Cygnus Loop, HB 21, CTA 1, Tycho, and HB 9. We provide new measurements of the polarized synchrotron radiation in the microwave range. The intensity and polarization

The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits. We analyze an asteroidal grazing meteor (FH1) recorded by the Finnish Fireball Network on October 23, 2022. FH1 displayed a likely hyperbolic orbit lying on the ecliptic

The radiation-induced polymerization of indene with a γ radiation source was studied at different dose rates (1, 2, 4, 6 kGy/h) and absorbed doses up to 400 kGy. The polymerization rate was determined through the thermogravimetric analysis and the spectrophotometric analysis of the irradiated indene solutions. With the two complementary methods the
