The Faint Young Sun (is not a) Problem
The apparent paradox of an early warm wet Earth but wimpy young sun may be solved by improved constraints and sophisticated atmospheric models.
Remnant Tales: Uncovering the Link Between Type Ia Supernova Ejecta and Planetary Nebulae
How Do Planetary Nebulae Influence the Evolution of Type Ia Supernovae?
Getting to Know Your Friendly Neighborhood Extremely Low-Mass White Dwarf
Meet our neighbor, the closest known extremely low-mass white dwarf.
Meet the AAS Keynote Speakers: Dr. Jennifer van Saders
Long-term space missions have left us with a wealth of stellar data. Come to Dr. Jennifer van Saders’s talk at #AAS235 to learn more about how these data, along with stellar models, can reveal a star’s evolutionary past and future.
You Spin me Right Round: Stellar Rotation with Asteroseismology
All stars rotate, and stellar rotation can impact a star’s evolution greatly. However stellar rotation remains poorly understood. Can studying stellar pulsations shed light on this topic?
The slowly cooling white dwarfs who say Ne!
A previously unexplained branch of cooling white dwarfs is likely a traffic jam caused by an 8 billion year delay in cooling. A heavy isotope of neon settling down into the core of the star could be the source.
