Conclusion

Our survey of IC348 in the near-infrared wavelength JHK$_{s}$-bands reveals many properties of the cluster. We performed photometry on 117 stars in each of the wavelength bands. The apparent magnitudes of our stars ranged from about 7.5 to 14.5 magnitudes in the H-band. This shows a wide range of main sequence stars of different spectral types. The color-magnitude and color-color diagrams for our cluster showed a significant amount of reddening in our cluster. Comparing these to the control field, we see that this reddening is most likely due to the interstellar dust found within our cluster as there is significantly less reddening in our control field. We determined the average extinction in the K-band to be about 0.5 magnitudes which corresponds to a visual extinction of about 8.929 magnitudes of extinction. Most of the stars found in our cluster were determined to be main sequence stars as they fell within the normal reddening region on the color-color diagram. About 15% of the stars in our cluster are possible T Tauri or proto-stars. We determined the age of the cluster to be about $5 \times 10^{6}$ years old by comparing our luminosity function to the model luminosity function and the dimmest star observed in our cluster was found to have a mass of 0.25M$_{\odot}$-0.47M$_{\odot}$.
