Scientific paper

In the course of a long-term radial velocity survey of about 100 southern pre-main-sequence (PMS) stars, we have discovered two spectroscopic PMS binaries. One is the weak-lined T Tauri star Haro 1-14c in the Ophiuchus clouds, which has a spectral type of K3 and is a member of the visual Haro 1-14 binary with a separation of 12.9". Haro 1-14c is a single-lined spectroscopic binary with a very long period of 591 days. The other is Parenago 2494, a weak-lined T Tauri star with a spectral type of K0 located in the Orion cluster. It is a double-lined spectroscopic binary with a period of 19.5 days. Our photometric monitoring shows that P2494 is a low-amplitude variable with a period of 5.77 days. We have determined accurate orbital elements for both binaries. We further discuss five low-amplitude velocity variable stars, which are possibly additional spectroscopic PMS binaries.
