Hints of a physical origin for the S8 tension Nat. Astron. (IF 14.1) Pub Date : 2024-04-15 Morgan Hollis
The open problems of the S8 tension and its close cousin, the Hubble tension, are some of the key cosmological challenges to the reigning champion of models of the Universe, ΛCDM. Undetermined systematic effects in the measured datasets are often invoked in an attempt to explain these tensions, however S.A. Adil et al. suggest a physical origin of the discrepancy, based on a Bayesian prior analysis

Expanding our limits with Euclid Nat. Astron. (IF 14.1) Pub Date : 2024-04-15 Luca Maltagliati
Euclid is the latest space telescope launched by the European Space Agency, on 1 July 2023. By surveying a third of the sky during its 6-year nominal mission with its two cameras, covering the visible and near-infrared range between 0.53 and 1.85 µm, Euclid is focused on understanding the role of dark energy and dark matter in the evolution of the Universe. However, Euclid will provide insight in other

Rapidly rotating or not? Nat. Astron. (IF 14.1) Pub Date : 2024-03-20 May Chiao
Evolved stars are expected to rotate, but ALMA observations of a dipolar velocity field at Betelgeuse suggest an extremely rapid rotation rate of 5.47 ± 0.25 km s-1, which is two orders of magnitude faster than predicted. Ma et al. test whether the dipolar structure could come from a nonrotating star instead. For instance, two large surface convective cells moving in opposite directions could mimic

TheCannon for abundances in solar analogues Nat. Astron. (IF 14.1) Pub Date : 2024-03-20 Luca Maltagliati
Various observations indicate that the Sun is depleted in refractory elements compared to the majority of Sun-like stars. Rayna Rampalli and colleagues extract abundances of such elements in thousands of Sun-like stars from spectra obtained by different surveys, in order to confirm the depletion and set constraints on its causes. The authors use TheCannon, an algorithm that is trained on a highly precise

The (probable) gas-rich nature of K2-18 b Nat. Astron. (IF 14.1) Pub Date : 2024-02-21 Luca Maltagliati
The nature of exoplanet K2-18 b is under intense debate. A recent theory, purportedly supported by JWST data (Astrophys. J. Lett. 956, L13; 2023), suggested that this 2.6-R⊕ planet in the classical ‘habitable zone’ of its star has a thin hydrogen-rich atmosphere but a water-rich interior and a global liquid water ocean — a ‘Hycean’ world — boosting its habitability prospects.

The JWST observations in the top left corner show bright spiral arms composed of stars, gas and dust, whereas in the HST image, bottom right, the spiral arms are dark. That is because dust absorbs UV and visible light, re-emitting it at infrared wavelengths. In the JWST image, the spiral arm material appears
