HD 235349 in comparison to several major types of chemically peculiar early-type stars as a function of stellar T_eff. Top panel:helium abundance in HD 235349 relative to the Sun, with the comparison sample from Ghazaryan et al. (2018, 2019) plotted in color. Middle and bottom panels:same as above, but for manganese and phosphorus. The gray region in the middle panel indicates the T_eff range wherethe Mn enhancement should drop off toward higher temperatures (Alecian & Michaud 1981).
