| Title | The Helium Abundance in the Metal-poor Globular Clusters M30 and NGC 6397 |
| Abstract | We present the helium abundance of the two metal-poor clusters M30 and NGC6397. Helium estimates have been obtained by using the high-resolution spectrograph FLAMES at the ESO Very Large Telescope and by measuring the HeI line at 4471 A in ... |

| Title | Near-Infrared Photometry of the Core-Collapsed Metal-Poor Globular Cluster NGC 5946 and NGC 7099 |
| Abstract | Moderately deep near-infrared images are used to investigate the photometric properties and spatial distribution of bright giants near the centers of the core-collapsed globular clusters NGC 5946 and NGC 7099. The former cluster is located ... |

| Title | C-M diagram and luminosity function of the Galactic globular cluster NGC 7099. I - Photographic photometry |
| Abstract | New photographic photometry of about 4400 stars in the field of the Galactic globular cluster NGC 7099 = M30 is presented. A C-M diagram and a luminosity function are obtained from this photometry. The distance modulus is estimated at 14.5 ... |

| Title | Magnitudes and colours for stars in the central part of the globular cluster NGC 7099 (M30) |
| Abstract | A color-magnitude diagram for 184 stars (V less than 17) in the central part of M30 (r in the 0-30 arcsec range) is presented. B and V radial variations of surface brightness are also presented. A slight color gradient is detectable in the ... |

| Title | Photometry in the central region of the globular cluster NGC 7099 |
| Abstract | The results of iris photometry in the UBV system on short exposure plates of M30 (NGC 7099) are discussed. The photometry is given for the bright stars within a radius of 10 to 90 arcsec from the cluster center. A factor-of-two deficiency o... |

| Title | The mean sequence of the metal-poor globular cluster M30 (NGC 7099) |
| Abstract | Main-sequence photometry, which is used to deduce the age of globular clusters, is presented for 673 stars in the globular cluster M30. The 3.6 m telescope at ESO, and the 1 m Yale and the 4 m telescopes at CTIO are among the locations wher... |

| Title | The colour-magnitude diagram of the globular cluster NGC 7099 |
| Abstract | UBV photometry of the globular cluster NGC 7099 is reported. The ultraviolet excess of D(U-B)=0.33 mag shows that NGC 7099 is an extremely metal poor cluster. The colour-magnitude diagram shows a strong blue population of the horizontal bra... |
