Haven't posted here much lately, but I figured @sciencesocks.bsky.social would have words for me if I didn't promote Merel's episode of the #astrophysics #podcast!
Dr. Merel van 't Hoff tells us all about the environments that new solar systems are born in! Check it out!

We're recording this episode soon, so in case you have any astronomy/astrophysics/science questions for us please post them here! The weirder the better. Also feel free to just ask about our lives. We're soliciting questions from a variety of sources! 🔭🧪
For the next episode of the #podcast, I hope to do an astrophysics Q&A. I invite you to reply with any questions about astrophysics, or questions about what it's like to be a scientist. To my scientist friends: feel free to reply if you like; just know I may quote your response in the podcast. 🧪🔭

The little one refuses to sleep unless Mama's in the room. So I've tried playing her episodes of the #podcast featuring the voice of Dr. Polin @therocketscientess.bsky.social . Not sure if it's working but maybe some of that astrophysics will absorb into her brain and she'll become a genius 🔭

I am now convinced that the words to "hush little baby" were completely improvised on the spot by two very tired parents. Because that's the only way I know how to do that song.

I'm creating a pinned thread here, I'm hoping to get comments from scientists and non-scientists alike. I'm interested in your answer to the following question:
In your opinion, why should we study astrophysics?

Very impressive astro seminar yesterday by @whereisyvette.bsky.social -- Incredible new data on tidal disruption events (TDEs), it pays to keep looking in the radio! 🧪🔭
(This plot is old data from 3 years ago -- you'll have to ask Yvette if you want the latest, but the light curve is still rising!)

Quantifying Advantages of a Moving Mesh in Nuclear Hydrodynamics
Many astrophysical explosions, such as type Ia supernovae, classical novae, and X-ray bursts, are dominated by thermonuclear runaway. To model these processes accurately, one must evolve nuclear react...
