Distance estimates based on low-resolution spectroscopy and Two Micron All Sky Survey (2MASS, Cat. ) J magnitudes are presented for 322 nearby candidates from Luyten's NLTT...

Table 1 lists 405 periodic variable stars we found in the area of NGC 2264 between. It contains information of the position, brightness, colours, and period of these stars. It...

The results of a deep mid-IR ISOCAM survey of the L1551 dark molecular cloud are presented. The aim of this survey is a search for new YSO (Young Stellar Object) candidates,...

Table 4 lists the 10554 stars in the area of NGC 2264 between I_C_=9.8mag and I_C_=21mag on which we did photometry. It contains information on the position, brightness, colours...

We present the results of a multiband survey for brown dwarfs in the Chamaeleon I dark cloud with the Wide Field Imager (WFI) camera at the ESO/MPG 2.2-m telescope on La Silla...

We report the results of a synoptic study of the photometric and spectroscopic variability of the classical T Tauri star AA Tau on timescales ranging from a few hours to several...

We use a deep near-infrared census of the young stellar cluster IC 348 to construct and analyze its luminosity function. Our mosaic image of IC 348 covers the full extent of the...

We present an analysis of 32 high-resolution echelle spectra of the pre-main sequence spectroscopic binary AK Sco obtained during 1998 and 2000, as well as a total of 72...

We present the results of spectroscopic observations for 52 objects from the list of H{alpha} emission stars of Stephenson (1986ApJ...300..779S). Out of six known T Tauri stars...

Results of NIR (JHK) photometry for about 1000 stars in 10 fields around IRAS sources previously recognized as related to star forming sites in the Vela Molecular Ridge C and D...

Table 1 lists the 1562 stars in the Orion Nebula Cluster brighter than I=20mag on which we did photometry. It contains information on the position, brightness and variability of...

File table2 contains the values of the color indices: (b-y), m1, c1, H{beta}, from the Stroemgren photometry and the observational errors on these indices as given by the Hauck...

We present the results of deep (K_s_=18.9) sub-arcsec resolution (0.3") imaging observations of the Cederblad 110 region in the Chamaeleon I dark cloud. This region (roughly...

This table presents stellar atmospheric parameters, absolute magnitude, mass, age, equivalent width of the {lambda}6708 Li line, and non-LTE Li abundance. For the majority of...

Using speckle-interferometry we have carried out repeated measurements of relative positions for the components of 34 T Tauri binary systems. The projected separation of these...

File table1.dat contains near-infrared JHK magnitudes of a sample of 18 Vega-like and post-T Tauri stars observed by the EXPORT collaboration. File table2.dat contains...

We present proper motion measurements of pre-main sequence (PMS) stars associated with major star-forming regions of the southern hemisphere (Chamaeleon, Lupus, Upper Scorpius -...

We have monitored the photometric, spectroscopic and polarimetric variations of the classical T Tauri star (CTTS) AA Tau over a period of a month. The light curve consists of...

The pre-main-sequence (PMS) population in the mass range between =~0.2 and =~3M_{sun} in southern part of the star-forming region NGC 2264 has been studied, determining both the...

This table provides the list of stars observed but not resolved during the diffraction-limited survey of G and K Pleiades dwarfs. Previously known binaries, either photometric...
