Can a planet change the measured age of its parent star?
If we know a star’s rotation we can calculate its age. But what happens if this rotation is affected by a nearby massive planet? And how much will this change our age estimate?
Understanding how massive star clusters form in our Universe
Today’s post looks at an observational paper trying to understand how young massive stellar clusters form from their progenitor molecular clouds.
The “Turbulent” Relationship between Stellar Feedback and Magnetic Fields
Simulations of star formation with bipolar outflows show that the degree of turbulence in magnetic fields can have effects on how quickly stars accrete material and on the structure of their outflows.
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”!
