Using an Infrared photometer with InSb photovoltaic detector at the 182cm Copernicus telescope of the Asiago Observatory, Italy, we have measured theJHKL’ M magnitudes of 12 IRC sources 7 of which are very late type stars with [ICIT -K] greater than 5 magnitudes. These data have been fitted to blackbody distributions to obtain their effective temperatures. The present data, in combination with other available photometric data at longer wavelengths seems to indicate excess emission at 11 μm from sources 10066, 10510 and 10234, and at 19.8 μm from source 20052. The source 60098 shows extreme infrared colours.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
