| | NGC 2264: Information From Answers.com |
| | NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula and the Christmas Tree Cluster. | | | Both objects are located in the Monoceros constellation and are located about 800 parsecs or 2600 light-years from Earth. | | | It may not have been reviewed by professional editors (see full disclaimer) |

| | The main feature of this object is its filamentary structure. | | | This object may be improperly designated as NGC 7023 in most listings. | | | It was given two NGC designations because (in small telescopes) its bi-lobed structure gives the appearance of two distinctly separate objects. |

| | [79.08] Coronal Activity in Low-Mass Pre-Main Sequence Stars: NGC 2264 |
| | Extensive optical photometry, classification spectroscopy, and proper motions, obtained from recent ground-based surveys of this region, were used to identify the most likely optical counterpart to each X-ray source. | | | This research was funded in part by the SAO Summer Intern Program and NASA grant NAG5-8120. | | | The X-ray cumulative luminosity function for solar-mass stars in NGC 2264 shows that most of the low-mass members probably have X-ray luminosities similar to those seen for the X-ray brightest members of older clusters such as IC 2391/IC 2602 (age ~ 50 Myr) and the Pleiades (age ~100 Myr). |

| | I wanted to determine the spectral types of these stars, but since the spectra spanned the range 3690-6960 Angstroms, I had to extend the MK classification system to these red wavelengths. | | | This instrument enabled high quality polarimetric maps to be made of sources such as Sharpless 106, Sharpless 140, and also a region in NGC 2264. | | | Using spectra published in the literature, temperature and luminosity sensitive features were identified and this extension was accomplished. |

| | We proposed the hard X-ray observations of the embedded population of PMS stars and protostars in the NGC 2264. | | | Recent molecular and NIR observations of relatively large regions of sky revealed that the dense and massive clusters are the units of star formation in a giant molecular cloud, which is usually associated with OB association. | | | They appear to be birthplace of most OB stars, and the cluster-mode star formation is the dominat mechanism to form most stars in OB associations. |
