New pre-main-sequence stars in the Upper Scorpius subgroup of Sco–Cen [PDF]
, 2015 We present 237 new spectroscopically confirmed pre-main-sequence K and M-type stars in the young Upper Scorpius subgroup of the Sco-Cen association, the near- est region of recent massive star formation.

Lithium evolution in metal-poor stars: from pre-main sequence to the Spite plateau [PDF]
, 2015 Lithium abundance derived in metal-poor main-sequence (MS) stars is about three times lower than the value of primordial Li predicted by the standard big bang nucleosynthesis when the baryon density is taken from the cosmic microwave background or the ...

A CONSTRAINT ON THE FORMATION TIMESCALE OF THE YOUNG OPEN CLUSTER NGC 2264: LITHIUM ABUNDANCE OF PRE-MAIN SEQUENCE STARS [PDF]
, 2016 The timescale of cluster formation is an essential parameter in order to understand the formation process of star clusters. Pre-main sequence (PMS) stars in nearby young open clusters reveal a large spread in brightness.

The Rotation of Pre-Main Sequence Stars [PDF]
Highlights of Astronomy, 1980 Kraft (1970) obtained the rotational velocities for large numbers of stars located in the field and in clusters of different ages. He noted that (a) among the field stars those stars with strong Call K emission had larger rotational velocities than those without; (b) stars in the Hyades and Pleiades (which are much younger than the field) had both ...

On the origin of the correlations between the accretion luminosity and emission line luminosities in pre-main-sequence stars [PDF]
, 2015 Correlations between the accretion luminosity and emission line luminosities (Lacc and Lline) of pre-main-sequence (PMS) stars have been published for many different spectral lines, which are used to estimate accretion rates.

Mid-IR spectra of Pre-Main Sequence Herbig stars: an explanation for the non-detections of water lines [PDF]
, 2015 The mid-IR detection rate of water lines in disks around Herbig stars disks is about 5\%, while it is around 50\% for disks around TTauri stars. The reason for this is still unclear.

Limits on the magnetic flux of a pre-main sequence star [PDF]
International Astronomical Union Colloquium, 1991 AbstractWe attempt to detect a magnetic field on the weak T Tauri star, TAP35, via the enhanced equivalent widths of Zeeman-broadened absorption lines. We synthesize 25 Fe I lines, having a range of Zeeman sensitivities, using an LTE Stokes line-transfer calculation.
