Massive circumstellar disks accrete faster than low-mass ones
Do predictions from classical disk theory work with state-of-the-art measurements?
Conflicts between Expansion History of the Local and Distant Universe
New supernovae measurements and precise distance calculations lead to an interesting conflict in cosmological parameters in the universe, depending on whether a tool is used to probe the local or the distant universe. Read on to find out how!
Uncovering planets and stellar activity using only radial velocities
How do we model stellar activity to disentangle planet signals from stellar activity using only RVs?
Moon Zoo: Counting lunar craters with “citizen science”
Crowdsourcing provides a cheap and efficient way for astronomers to analyze features on the lunar surface.
Looking for Dwarf Galaxies with Cepheids: A Cautionary Tale
Today we use a new paper to revisit the possible dwarf galaxy discovered 90 kpc from the Milky Way.
Searching for white dwarf companions around millisecond pulsars
Images from the Hubble Space Telescope show that there are previously unknown white dwarfs orbiting around pulsar companions.
