Slowly Rotating Relativistic Stars: VII. Gravitational Radiation from the Quasi-Radial Modes

When a relativistic star rotates slowly and rigidly, centrifugal forces flatten it slightly, thereby catalyzing a small admixture of quadrupolar vi...

"The research for this paper was completed in 1972, and Jim and I began writing it in that same year but then got distracted for several decades by other projects. In 2000, Jim completed a first draft and gave it to me with some public fanfare on the occasion of my 60th Birthday Symposium. I then let it languish until Jim‘s 80th Birthday Symposium in 2019 ..."

Freedom is a heavy load, a great and strange burden for the spirit to undertake. It is not easy. It is not a gift given, but a choice made, and the choice may be a hard one. -- Ursula K. #LeGuin, "The Tombs of Atuan", Book #2 of #Earthsea

Is there something you always wanted to ask an astrophysicist? Here is your chance. I will try to answer as many questions as I can today. And if I enjoy it, we may repeat this later. Some background: I'm a high energy astrophysicist working on black holes, neutron stars, accretion and massive stars with a pretty broad knowledge of the whole astro field (I did teach it at uni level), but little to no experience with hobby observing or astrophotography. #AskAnAstrophysicist #AMA #astrodon

All the books I've read and don't remember in detail, have been firmly pressed into the foundation of who I am. You can't tell the individual books apart under the weight of the later experience, but they are there, shaping who I am, planting the seeds of today's thoughts and decisions. Every hero rising against injustice. Every warning of old science fiction books. Every friendship. Every moment of forgiveness. Every sacrifice for a better world. They all are there, making me me.

I'm adding to my book wishlist at least five times as fast as I read - and to my unread pile at least twice as fast 😬

~ Mediterranean cucumber & tomato #salad ~ I loooove a simple but delicious salad! Cucumbers (they do not have to come from your mother-in-law's garden, though mine did!), tomatoes and a red onion, all in small cubes. Add olive oil, mint chiffonade (fancy way to say leaves cut in thin ribbons), salt, pepper and, here comes the drink, a good portion of sumak. Don't skip the sumak. This is our favorite side with Börek, but it also works in so many other combos. #ViciCooks #kochen #food #essen
