Identifier: http://hdl.handle.net/1959.14/306635
Description: The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iro ... More

Identifier: http://hdl.handle.net/1959.14/337559
Description: We use the kinematics of similar to 200 000 giant stars that lie within similar to ~1.5 kpc of the plane to measure the vertical profile of mass density near the Sun. We find that the dark mass contai ... More
