Abstract
The possibility that unknown sources of opacity may exist in the M2V spectral class star, HD 95735, has been investigated. The factor by which the known sources of opacity should be multiplied to obtain the opacity obtaining in the star is estimated by comparing the total pressure obtained from model atmosphere and that from pressure broadened wings of λ4227 line of Ca I. This factor is close to unity if the effective temperature of the star is about 3400°K, and it increases for lower effective temperatures. The effect of metal abundance has also been considered.
