In the paper ``Oxygen in the Very Early Galaxy'' by Garik Israelian, Rafael Rebolo, Ramón J. García López, Piercarlo Bonifacio, Paolo Molaro, Gibor Basri, and Nataliya Shchukina (ApJ, 551, 833 [2001]), in Figures 7, 8, 9, 10, and 11 the OH oxygen abundance for BD +23°3130 is slightly misplaced. The correct figures, which were not included because

We have obtained low resolution optical spectra of 15 isolated planetary mass objects (IPMOs) in the sigma Orionis cluster, and derived spectral types by comparison with nearby M and L dwarfs. The spectral types are in the range late M - mid L, in agreement with our expectations based on colors and magnitudes for bona fide members. Therefore, most

An analysis of the collapse of the Twin Towers is carried on with the aid of simple mechanical laws. The motion of the collapse front is calculated in terms of geometric and energetic quantities.

We present a total of 12,436 photometric measures of 371 field stars of 26 quasars in the visible (UBVRI) and 22,276 photometric measures of 122 field stars of 13 quasars in the near-infrared (JHK), giving a total of 34,712 measures. Of these, 115 stars in 12 fields are calibrated in both ranges. One further field, Mrk 421, was calibrated, but on

We present a homogeneous set of stellar atmospheric parameters (Teff, logg, [Fe/H]) for a sample of about 700 field and cluster stars which constitute a new stellar library in the near-IR developed for stellar population synthesis in this spectral region (λ8350-9020). Having compiled the available atmospheric data in the literature for field stars
