Movement in the Dust: Detecting Planetary Candidates via Disk Kinematics?
In today’s paper, the authors analyze millimeter and submillimeter ALMA observations of a protoplanetary disk, and find kinematic signs of candidate companions within!
Dynamical Duo: An Updated Understanding of the Orbits of the Two Giant Planets in the HD 45354 System
In today’s paper, the authors take another look at the HD 45354 planetary system, and come to new conclusions about the orbit of the two gas giants within!
Could Stripped Stars be False Positives in the Search for the Missing Black Holes?
The authors of today’s article argue that stripped B-type stars could be a source of false positives in the search for quiet, stellar-mass black holes in the Milky Way
Defining Gravity: Can Wide Binaries be a Definitive Test of Modified Newtonian Gravity Theories?
Today’s paper posits that precise observations of wide binaries can be used, in conjunction with simulations, to test the validity of modified gravity theories!
#BlackInAstro: AAS237 Special Session on Anti-Blackness in Astronomy
As our first post for #BlackInAstro for Black History Month, we share our coverage of a special session from the January 2021 meeting of the American Astronomical Society.
Glimpsing Dark Objects with Gaia
Today’s authors work out a full orbital solution for a binary microlensing system, indicating the method’s potential to probe the mass distribution of dark objects.
