Mass loss upper limits for A and F dwarfs

摘要: The upper limits of the ionized mass losses A- and F-type main sequence stars are obtained with VLA to investigate theory that pulsationally driven winds contribute substantial loss in stars. found be at least one order magnitude lower than mass-loss loci proposed by Willson et al. (1987). Because any wind flowing from should detectable, notion A dwarfs evolving into G cannot supported amount F shown losing.
