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

Cosmic recipe book updated Nat. Astron. (IF 14.1) Pub Date : 2024-03-20 Paul Woods
A pioneer of Open Science in astronomy, the UMIST Database for Astrochemistry (UDfA) has recently released its sixth iteration and now contains 8,767 gas-phase chemical reactions — involving 737 chemical species — and their reaction rate coefficients. This is an increase of more than 40% in comparison to the previous version, released in 2013. The growth reflects the number of reaction rates measured

Sowing the seeds of early galaxy evolution Nat. Astron. (IF 14.1) Pub Date : 2024-03-19 Morgan Hollis
The emergence of massive black holes early on in the history of the Universe is a topic brought to the fore by recent JWST results. If these behemoths formed according to the conventional paradigm — with growth mechanisms taking place over billions of years — then how can there be as many as we now observe, already in existence so soon after the Big Bang? Roberto Maiolino and collaborators seek to

As it travels through the corona and into the heliosphere, a CME interacts with the environment, thereby losing coherence once it arrives at Earth. But with BepiColombo (BC) and Parker Solar Probe (PSP) near Mercury at the time — only 0.35 au from the Sun — Palmerio et al. were able to track the timings of CME-related features (in sequence: shock, sheath, ejecta) and compare the data between the probes

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 multiwavelength views present different, but complementary, impressions of the galaxy. 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

The Sun appears to be a fairly normal main-sequence star from the outside, but might it contain a small primordial black hole? If so, it would be partially powered by accretion luminosity from the microscopic black hole in its core and would follow an evolutionary path that diverges from a typical G-type dwarf.
