A clash of disks: the traumatic life of the HV-DO Tau system
In the right conditions, protoplanetary disks might retain evidence of past encounters and can tell us more about the life story of the stellar environment they reside in.
Astrobites at AAS 233: Day 1
We report on Day 1 of the winter AAS meeting in Seattle, WA. Highlights include a discussion of interstellar asteroid ‘Oumuamua, an overview of first results from TESS, a dragon in the Orion Nebula, and a look at the role identities play in astronomy.
Meet the AAS Keynote Speakers: Dr. Caitlin Casey
Some galaxies are easy to find—others, like dusty galaxies with extreme star formation, are a bit harder to track down. Come to Professor Caitlin Casey’s #AAS233 talk to learn how we can find these galaxies in the “obscured early universe”!
Traits of Accreting Galaxies
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
Mixing up a Batch of Stars
We can learn a lot about the history of the universe from the stars we see in the night sky today. In today’s astrobite, we look at the history that certain carbon-enhanced, metal-poor stars might be trying to tell.
The strange case of quiescent and dusty
A series of papers between two research groups, investigating the nature of an unusual distant galaxy.
