Geneva photometry of the open cluster NGC 2451 and its exceptional Be star HR 2968 ? , ? ?
During many years, several authors discussed whether NGC 2451 was a real open star cluster or not. By using parallaxes and proper motions from Hipparcos satellite, and Geneva multicolour photometric measurements of 64 stars, the existence of two clusters A and B is confirmed. Distances and Geneva colour excesses E[B − V ] are respectively 197 pc, 0.01 and 358 pc, 0.12 for NGC 2451 A and B. The ...
متن کاملGeneva photometry of the Be star HR 1960: periodicity and extremely small amplitude
The Be star HR 1960 has been monitored from 1982 to 1998 in Geneva photometry and from November 1989 to March 1993 by the Hipparcos satellite. This star shows two kinds of luminosity variation: i) The mean luminosity in V has slightly increased, by 5 millimags, during the survey (long-term variation); ii) A periodic light variation with a period of 395 d has been observed, in both Geneva and Hi...
متن کاملComparison of the deterministic and fuzzy approaches in HR planning
Supplying required human resource is one of the strategic goals of an organization. Therefore, organizations plan and predict the required human resources in order to prevent this problem. Present study using practical approach seeks to assist organizations to achieve their various goals in human resources planning. The designed model in this study clarifies vague, inaccurate, and fuzzy exp...
متن کاملMeibomian Gland Changes in the Rhino (hr^hr*) Mouse
The rhino mouse, a single gene recessive mutation, is characterized by abnormal epidermal differentiation and maturation leading to the loss of hair at 1 month of age as well as follicular and epidermal hyperkeratoses. We evaluated the lids and corneas of nine rhino mice and their normal litter mates at various ages from 3 months to 1 year. Tissue specimens were studied by light microscopy, sca...
