Buy me a coffee?
Writing this blog is a labour of love, and one which I evidently need a little encouragement towards on occasion. If you like what I write, the best way to show your gratitude would be to fuel my caffeine addiction and buy me a coffee to say thank you. All coffee donations are gratefully accepted!

Papers!
So I have a nice little shortlist of papers which I might present at next week’s journal club. In fairness, it’s still not a very short shortlist, so I should probably dismiss a couple of these before I offer them … Continue reading
Portraits of Scientists
New Zealand born photographer Max Alexander has taken a truly fantastic set of portraits of a number of astronomers. These are just two of them — go to his website and have a look at the rest! With thanks to … Continue reading
Tiny Twins
It’s been known for a while now that there’s no clear boundary between a very large planet and a very small star. 1995 saw the discovery of the curious brown dwarf stars. Stellar inbetweeners, too small to be true stars … Continue reading
Some bookmarks…
I bookmark a lot of things, some of which prove to be more useful than others. In particular, I’ve been looking recently at resources pertaining to stellar spectra and exoplanets. Here are a few of the more interesting links I’ve … Continue reading
Introduction to Nuclear Astrophysics
All written up and cunningly disguised as a paper, this appeared on arXiv a few days ago. It’s a write-up of a lecture given at a recent summer school in Italy, by Dr. Christian Iliadis (Uni. North Carolina), covering some … Continue reading
Looking for planets? It’s all about the lithium!

I am one of 18-35% of the human population with a photic sneeze reflex! If I step out of a dark building into full bright sunlight, it makes me sneeze. It always has. When I was a kid, I used … Continue reading
A Universe of Marshmallows
I fear that even contemplating writing the tirade of geekery that’s about to ensue might forever concrete my reputation as a mad scientist. Although I don’t really have a reputation as a mad scientist. Yet. This started out as a … Continue reading
Poisonous gas bubble!
Stars like blowing bubbles. Especially when they get old. TT Cygni here, is no exception. Except that bubbles like this one are rather a lot more lethal than the kind you’d blow with soapy water. An ageing giant, TT Cygni … Continue reading
A chill stellar wind…
Thermodynamics may be very good at putting freshers to sleep during Monday morning lectures, but it really is a fundamental piece of modern physics. Bluntly, you don’t argue with thermodynamics. Originally developed to increase the efficiency of steam engines, the … Continue reading
