Hello new followers! I'm Shishir, and I study all things exoplanets. Below is an artist's rendition of Gliese 12 b, a planet I co-led the discovery of this year. I plan to post more cool things I come across in my research. I also love astrophotography, so stay tuned for pretty space pictures! 🪐🔭

Jupiter rotation timelapse with lo (and shadow) transit! Taken Feb 8th from my backyard. Went out at 5 min intervals to capture a video. From each of these, the best 10% were stacked to produce a single frame (lucky imaging).

Do you like binary stars? How about Wolf-Rayet stars? May I introduce you to my new chapter on what happens when you put WR stars in binaries... awesome colliding wind binaries!
This should be a handy resource whether you're new to or knee-deep in the field! 🔭(1/?)

Deeply sad to hear of Prof. Fajan's passing--a deeply inspiring and dedicated educator at Berkeley.
When I took his instrumentation class, COVID switched us to remote mid-semester. He ended up hand soldering Arduino kits and mailing them to us for the final project.

Devastated to learn that Joel Fajans has recently passed away - one of the most inspiring lecturers I ever had as a student. He was so creative and engaging. I think about his lecture on the physics of bikes every week!

Comet Tsuchinshan Atlas has been quite a show over the last month. Some final shots before it fades away from us. One of the best comets I’ve see for a long time.

My first PhD paper is on arxiv today!
Rotating planets are slightly wider at their equator compared to the poles. Saturn in our Solar System (below, minus the rings), is about 10% oblate! Can we detect this shape difference in transits from JWST? (1/N)

Comet A3 Tsuchinshan-ATLAS Timelapse ☄️
I've been photographing this comet for the past couple days, and I've been blown away by how bright it is. Can't wait to get back out for more tonight!
Location: Queensland, Australia
Equipment: Sony A7IV with 100mm lens, tracked.

Tsuchinshan-ATLAS growing a nice tail now. Still difficult to see without binoculars, so low to the horizon before sunrise.
