Guest: Fast and Curious: Rotation of Blue Straggler Stars in NGC 1851
What are blue straggler stars and how are they formed? By using spectroscopy, today’s authors explain the link between this question and how fast these objects spin!
How Galaxy Mergers Can Bridge The Stellar Age Gap in Spiral Arms
Can galaxy interactions help young and old stars in spiral arms get to know each other? These authors’ simulations may have an answer!
Can’t we just take a picture of an exoplanet?
If we want to know about the conditions for life on an Earth-like exoplanet, can’t we just take a picture of it? One where we can see continents, clouds and potential biospheres?
The short answer is we can’t. The long answer as to why not is found in today’s bite.
How to ID some extrasolar dusty snowballs
Exocomets are becoming more interesting, given their detections are more promising and well studied. So, naming them is of more importance now than ever. Today’s bite summarizes a paper that proposes a nomenclature for exocomets.
Feed the Fire, Fade the Metals
Are cosmic clumps “homegrown”, or fueled by fresh inflow? Today’s authors find that star-forming clumps are usually more metal-poor than the disks around them.
A Potential New Piece of the “Little Red Dot” Puzzle
Today’s paper presents an intriguing new object, which may be a early-Universe supermassive black hole shedding its gas cocoon!
