    Condensation of dust around the Wolf-Rayet star WR 125
    Infrared photometry of the WC7-type Wolf-Rayet star WR 125 (MR 93) in 1981-91 shows a 10-fold rise in the 3-4 micron flux during 1990-91. This, together with...

    Magnetic and Rotational Evolution of ρ CrB from Asteroseismology with TESS
    During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent...
