Pre-main-sequence variability across the radiative–convective gap
We use I-band imaging to perform a variability survey of the 13-Myr-old cluster h Per. We find a significant fraction of the cluster members to be variable. Most importantly, we find that variable members lie almost entirely on the convective side of the gap in the cluster sequence between fully convective stars and those which have a radiative core. This result is consistent with a scenario in...
متن کاملPhotometric variability of the Pre-Main sequence stars
The photometric and spectral studies of the pre-main sequence stars are very important for understanding of the early stages of stellar evolution. Depending of the initial mass the young stars pass through different periods of stellar activity. The most prominent manifestations of this activity are changes in the star brightness with different periods and amplitudes.A short review on photometri...
متن کاملStructure and Evolution of Pre-Main Sequence Stars Citation
Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that this emission was of thermal nature and primarily originated from coronal activity (magnetically confined loops, in analogy with Solar activity) on contracting young stars. Broadband spectral analysis showed that the emi...
متن کاملRotational evolution of pre-main sequence stars in Lupus
Wepresent results of a study of the rotational periods of Post-T Tauri stars (PTTSs) in the Lupus star forming region. These stars have been discovered by spectroscopic follow-up observations of ROSAT x-ray sources. Photometric observations have allowed to determine their luminosity, and by comparison with theoretical evolutionary tracks they were found to be significantly older on average than...
متن کاملPre-main-sequence Lithium Depletion
In this review I briefly discuss the theory of pre-main-sequence (PMS) Li depletion in low-mass (0.075 < M < 1.2M⊙) stars and highlight those uncertain parameters which lead to substantial differences in model predictions. I then summarise observations of PMS stars in very young open clusters, clusters that have just reached the ZAMS and briefly highlight recent developments in the observation ...
