Abstract
We present spectroscopic observations of 33 emission line stars from the Sanduleak & Stephenson's (1973) list. This work is part of a program to investigate emission-line objects in the southern hemisphere whose nature is not well established in the literature. The objects were observed at two different spectral regions providing full coverage in the 3100-8700 Å interval. In this paper we describe the main spectroscopic features and discuss the nature of the objects. It is proposed that 16 of them are Be stars, 5 are peculiar Be stars, 4 are T Tauri stars, 7 are M-type stars with emission-lines and 1 is a Herbig object.


Key words: stars: emission-line, Be -- stars: general -- stars: pre-main sequence -- stars: late-type

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
