Main sequence companions to white dwarfs II: the age-activity-rotation relation from a sample of Gaia common proper motion pairs
A. Rebassa-Mansergas, J. Maldonado, R. Raddi +8
Magnetic activity and rotation are related to the age of low-mass main sequence stars. To further constrain these relations, we study a sample of 574 main sequence stars members of…
