It's only since Cecilia Payne's PhD thesis in 1925, that we know what the stars - and our Sun - are made of: mostly hydrogen.

Her thesis was described as ""the most brilliant PhD thesis ever written in astronomy" and it extremely readable: https://ui.adsabs.harvard.edu/abs/1925PhDT.........1P/abstract

Yet It took until 1956, 10 years before her retirement, for her to become full professor - because women were barred from becoming full professors at Harvard.

(Posted because she was born ).

🥰 When the colloquium speaker had the sticker of your drawing on their laptop 💚 And they are not even one of my collaborators!

Bailed out on a hike (my vertigo did not like me today morning), doing some art instead.

We are celebrating Christmas at partner's parents with the same raclette grill as 20 years ago - which is pretty impressive, but not quiet as much as the Voyager spacecrafts 😅 Voyager 2 was launched on August 20, 1977 - still working, still teaching us new things about the most external parts of the solar system.

With many thanks to @schnedan for the idea to draw Voyager :)

Oh, apparently yesterday was and I missed it! I am Victoria and I am doing , mainly focusing on astronomy & astrophysics () and on
& research commentary.

You can fine more of my doodles here: https://www.sternwarte.uni-erlangen.de/~grinberg/#doodles

And an introduction to my process & an encouragement for other researchers to do art here: https://mastodon.social/@vicgrinberg/111115356974247400

My black and white and grey digital sketch of Cecilia Payne Gaposchkin. Above it, a citation from her thesis: 'The application of physics in the domain of astronomy constitutes a line of investigation that seems to possess almost unbounded possibilities'. Slightly in the background sketches of the energy levels in the hydrogen atom (orbital co-sketched) and a star with sun spots and loop/protuberances. Name and citation underlines in red, everything else is black and white.
A black & white stylized sketch of things falling into a black hole: a cat, a whale, a star, an apple, a physics book, a bowl of pasta, an astronaut ... And the final black hole only has mass, angular momentum and charge (marked as words).
A stick figure balancing on an unicycle on a wire above a canyon, biking towards a sign saying 'a job (maybe)' while the wire is fraying apart. The figure is carrying a precarious amount of boxes, labelled bureaucreacy, two-body problem, anxiety, childcare, finances, living in a foreign country, loneliness, impostor syndrome, depressopn, career insecurity. Next to it title of the session 'Healthy Careers in Astronomy', the names of the two convenors (V. Grinberg, M.S. Pawlowski) and a list of speaker names

1/16 This July, I gave an invited talk in the "Communicating Science Through Art" session at the European Astronomical Society annual meeting, organized by the amazing @theastrophoenix . And I thought it may be something that would also interest you folks.

The aim of the talk was partly to give people insight into my why & how of my art. But mainly to encourage others to just try. In a very subjective manner.

A thread: 🧵

  • collecting art supplies or learning new tools is a hobby of it’s own and not the same hobby as making art
  • understanding of basics is helpful: how to build up a page? how do shadows work? how to colors work together?

And that's it. I do hope you find it useful and maybe encouraging to try on your own!

I'll be giving a version of the above talk 👆 in one of our seminars in less than one hour. Kinda nervous!

@vicgrinberg@mastodon.social avatar

For all the folks starting their (or their master thesis) today - a reminder why your PhD advisor can solve a problem so "easily" ...

@vicgrinberg@mastodon.social avatar

Want to know what my research is about? Follow this thread 🧵 based on a 10min talk I've drawn for a meeting.

The talk was aimed at non-specialist space science colleagues (not the general public!). The slides were built up step by step, but I'm omitting this here & showing only the final graphs, less this becomes a 34-part thread. 11 is plenty enough!

So: "Understanding Winds of Massive Stars Using High Mass X-ray Binaries"

What next for this research?

  1. Apply methods to more sources! Also to build a sample and test different star & binary properties e.g. https://ui.adsabs.harvard.edu/abs/2023A%26A...674A.147D/abstract & https://ui.adsabs.harvard.edu/abs/2021MNRAS.501.5646M/abstract
  2. Refine methods (better statistics tools, take more effects into account ...) - e.g. https://ui.adsabs.harvard.edu/abs/2023arXiv230414201H/abstract
  3. And of course we hope for better data with and missions!

Vacation means more postcards! 🎨

I was totally fascinated by the dark red cosmos. If I had a garden (and were garden person in general), I'd love to have them. These are from Arlington Court in Devon.

(As a fun side story: I spent half a day wondering where I heard of Arlington Court - only yo realize that Arlington is a suburb of Boston /Cambridge and that's while I know the name...)

Of course most of the cards are buildings again. This one is from - it was sunny when we entered the village and it poured when we were at the other end!

vicgrinberg,
@vicgrinberg@mastodon.social avatar

And another one - St Ives has a lot of pretty buildings which were rather hard to photograph given the narrow streets and the amounts of people.

My friend thought it was too much, but I kinda loved the buzz of the (very touristy) town and the many little shops.

@vicgrinberg@mastodon.social avatar

And the last postcard of the Devon + Cornwall set. Also my favorite.

was... over-sugared is perhaps the right word. But the harbor was very cool (including some swarming fish), I got to pet a donkey and bought some handmade pottery. Not sure it would be worth driving and paying the parking fee, but it was a great mid-point for a hike!

A well spent morning + early afternoon 🎨

I haven't touched watercolors since October - a reminder of how full and stressful a time it has been. Not that the stress got less, but trying hard to truly disconnect this week.

And one more, this time loosely based on a house in L’Ospédale.

@vicgrinberg@mastodon.social avatar

I guess if science & science politics annoy me enough, I may just open a travel postcard shop as an alternative career 😅

vicgrinberg,
@vicgrinberg@mastodon.social avatar

And likely the last one for the Corsica series - I've got impatient towards the end of this one, a sure sign that my creative juices are running out for the moment.

I'm stupidly proud that the grapewines on this one actually look like grapewines (if they don't, don't tell).

Tomorrow, all six are going to be sent off to friends to hopefully make someone else than me happy 💚

vicgrinberg, to Cat
@vicgrinberg@mastodon.social avatar

It turns out are a lot like cats 😼 Especially, they play with their food 🐀

You don't believe me?

Remember how a plays with a mouse: catches it, releases it, catches it again, releases it again ... Turns out, black holes can do the same with stars: they can catch and partially disrupt a star, release it, wait until it approaches again, play with it a bit more, release it, wait for the next approach:
