Chromospheric emission of solar-type stars with asteroseismic ages
R S Booth, K. Poppenhaeger, C. A. Watson +3
Stellar magnetic activity decays over the main-sequence life of cool stars due to the stellar spin-down driven by magnetic braking. The evolution of chromospheric emission is well-…
An Improved Age-Activity Relationship for Cool Stars older than a Gigayear
R. S. Booth, K. Poppenhaeger, C. A. Watson +2
Stars with convective envelopes display magnetic activity, which decreases over time due to the magnetic braking of the star. This age-dependence of magnetic activity is well-studi…
New Periodic 6.7 GHz Class II Methanol Maser Associated with G358.460-0.391
J. P. Maswanganye, M. J. Gaylard, S. Goedhart +2
Eight new class II methanol masers selected from the 6.7 GHz Methanol Multibeam survey catalogues I and II were monitored at 6.7 GHz with the 26m Hartebeesthoek Radio Astronomy Obs…
