| Abstract: | We investigated the distribution of Neugebauer and Leighton's two micron survey (TMSS) stars on the {K - 12];12] - 25]} and {12] - 25];25] - 60]} planes. The frequency of circumstellar emission objects among B-K type stars is less than 5% while it reaches about 20% at M , 80% at stars with unknown spectra and 90% at carbon stars. |
