The distance modulus of the Small Magellanic Cloud based on double-mode Cepheids

open access: green, 2000
We employ the very recent photometric data of the OGLE project together with stellar atmosphere and linear pulsation models to determine the distance modulus of the Small Magellanic Cloud from its double-mode Cepheids. Based on the requirement of obtaining the same distance modulus DM from the two types of variables (fundamental & first overtone ...

STUDY OF THE INTERFRAGMENTARY STRAIN AND THE INTERFRAGMENTARY MODULUS WITH CHANGING THE DISTANCE BETWEEN PLATE AND FEMUR [PDF]

open access: hybridAmerican Journal of Applied Sciences, 2014
For several years the distance between plate and fe mur has been studied for preventing the damage to t he blood supply by the contact pressure between plate and femur. The Limited Contact Dynamics Compression Plate (LC-DCP) is normally used to create the dista nce by using the locking screws.

Two spectroscopic binaries in the open cluster M11 and their implication for the cluster distance modulus

open access: bronzeThe Astronomical Journal, 1989
Two single-lined spectroscopic binaries, MPS 926 and MPS 1223, have been identified among 30 giants surveyed in the open cluster M11. MPS 926 has a circular orbit with a period of 210 days; MPS 1223 has a highly eccentric orbit with a period of 660 days.

The distance modulus of the Large Magellanic Cloud: Constraints from RR Lyrae pulsation properties

open access: green, 1996
It has recently been suggested that the discrepancy between the "long" and "short" distance moduli of the Large Magellanic Cloud (LMC), as inferred from the properties of the Cepheid and RR Lyrae variables, respectively, might be due to the action of "third parameters" between the Galaxy and the LMC, which would make the RR Lyraes in the old LMC ...

The distance modulus of the Large Magellanic Cloud based on double-mode RR Lyrae stars

open access: green, 2000
We use double-mode RR Lyrae (RRd) stars from the MACHO variable star database of the Large Magellanic Cloud (LMC) to estimate its distance, by utilizing photometric data, linear pulsation and stellar atmosphere models. If we set E_(B-V)=0.11 and [M/H]=-1.5 for LMC, we get M-m=18.52 mag, which is in agreement with the value obtained from Galactic ...

Nonlinear Models of the Bump Cepheid HV 905 and the Distance Modulus to the Large Magellanic Cloud [PDF]

open access: bronzeThe Astrophysical Journal, 1997
Nonlinear pulsation models have been used to simulate the light curve of the LMC bump Cepheid HV 905. In order to reproduce the light curve accurately, tight constraints on the input parameters M, L, and T-eff are required. The results, combined with accurate existing V and I photometry, yield an LMC distance modulus of 18.51 +/- 0.05, and they show ...

A new convergent point and distance modulus for the Hyades from radial velocities

open access: bronzeThe Astronomical Journal, 1988
The dynamics of the Hyades open star cluster is investigated analytically on the basis of the photoelectric radial velocities reported by Griffin et al. (1988). The methods used to determine the radial-velocity gradient, convergent point, and distance modulus are described, and the results are presented in tables and graphs and characterized in detail.
