Which star has the highest mass loss rate? We have known lists of stars with high luminosity, temperature, mass, size, and much more. However, I have not seen a list that compares each star's mass loss rates. So, which star (or stars) have the highest mass loss rates, and is it going to be more likely to be an LBV, RSG, or a WR star?
Some very hot and massive stars have strong stellar winds, known spectroscopically as &quot;P Cygni profiles&quot; after the type star. P Cygni 'erupted' in the 17th century to magnitude 3 and is now visible as a mag.5-6 star near the central star of the 'Northern Cross' that is Cygnus. An ordinary pair of binoculars will show it easily. So P Cygni stars have probably the highest mass-loss rate as I believe you are thinking of.
