Before being locked in a basement at the TNG offices for two days of WEAVE Science Processing & Analysis meeting (my first as part of the CASU team!), I managed to check out the southernmost tip of La Palma 🌋

At NAM 2025 in Durham @nam25-durham.bsky.social Anke Ardern-Arentsen is speaking on Carbon-enhanced metal-poor stars as probes for early chemical enrichment. Anke has published in #MNRAS: academic.oup.com/mnras/articl...

Predicting metallicities and carbon abundances from Gaia XP spectra for (carbon-enhanced) metal-poor stars

ABSTRACT. Carbon-rich (C-rich) stars can be found at all metallicities and evolutionary stages. They are often the result of mass transfer from a companion

"Ending bullying and precarity should be Cambridge chancellor’s focus" says Prof Wyn Evans

"There is a need for University ombudsman to investigate cases of mismanagement or misconduct

I urge my fellow candidates for chancellor to back this call"

Ending bullying and precarity should be the Cambridge chancellor’s focus

In recent decades, the post has been seen as purely ceremonial. But there is precedent and justification for a more interventionist role, says Wyn Evans

Happy to announce that the line-detector.oca.eu website is now online!
It allows the user to select the stellar type, [M/H], λ- range, and resolving power and the page returns:
-purity of the line and minimum S/N required to detect it.
-interactive plot to identify the lines in the spectra

Such a good view for a meeting room, and the view at the dinner was amazing too 😍 @ Pristine collaboration meeting, Nice Observatory @obscoteazur.bsky.social

A view of Nice city and the Mediterranean sea, framed by a window inside the Observatory library. There are clouds in the sky and some raindrops on the window, but the view is amazing.

View of Nice by night, with many city lights below and still some sunset colours in the sky. Taken from Nice observatory, near the big dome (not visible)

For a recent outreach talk I created this visualisation of real stellar spectra (from the LAMOST survey) - showing a metal-rich, a very metal-poor, and a carbon-enhanced very metal-poor star with similar temperatures (~5000K). Look at those massive molecular carbon bands for the CEMP star! ✨🔭

The image shows three spectra from top to bottom (metal-rich, very metal-poor and carbon-enhanced very metal-poor, respectively), with each wavelength visualised by a coloured vertical line. The axis goes from ~380-700 nanometers. The metal-rich star has more and stronger dark lines than the metal-poor star, corresponding to absorption features. The carbon-enhanced metal-poor star has massive absorption bands, corresponding to molecular carbon absorption.
