![- [TOP] [X/Fe] vs. [Fe/H] for n-capture elements in the SMC. Abundance patterns are shown for Eu (leftmost panel), Zr (second leftmost) and Ba (second rightmost) and La (rightmost). Solid lines are genuine chemical evolution tracks for the reference models adopting Rubele et al. (2018) SFH (blue) and Massana et al. (2022) SFH (green), whereas shaded cyan and light-green regions are associated model predictions account for observational uncertainties (’synthetic models’). Data are from Anoardo et al. (2025, Eu) and Mucciarelli et al. (2023a, Zr, Ba, La) for SMC field stars (orange dots) and Mucciarelli et al. (2023b) for SMC GCs (black dots). Orange contour lines represent density lines of the observed stellar distributions in SMC field stars. - [BOTTOM] [X/Fe] vs. [Fe/H] for n-capture elements for the model adopting Rubele et al. (2018) SFH with increased MNS r-process production at low-metallicity (see Eq. (4)). Blue solid lines and cyan shaded regions represent genuine chemical tracks and model predictions accounting for observational uncertainties (’synthetic model’), respectively.

First Detection Of Ices In Intermediate-mass Young Stellar Objects Beyond The Milky Way
Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8-4.1 Msun) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC 346 star-forming cluster in […]

The Local Galactic Transient Survey Applied to an Optical Search for Directed Intelligence
We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence (SETI) sources in […]

Planet-forming Discs Lived Longer In The Early Universe
In 2003, Hubble spotted a massive planet around a very old star, almost as old as the Universe. This implied that some planet formation happened when our Universe was very […]
