A critical comparison of two of these studies — Mateo () and Elson, Fall, and Freeman (; EFF) — is papercitysoftware.com by: 2. The Large Magellanic Cloud (LMC) harbors a rich and diverse system of star clusters, whose ages, chemical abundances, and positions provide information about the LMC history of star formation.

Abstract. Luminosity and Initial Mass Functions (IMF) are determined for a sample of six Magellanic Cloud (MC) star clusters. The program objects span a large range in age (10 Myr to Gyr), and include the possibly very metal-poor cluster NGC in the papercitysoftware.com by: 2.

The Small Magellanic Cloud contains a large and active population of X-ray binaries. Recent star formation has led to a large population of massive stars and high-mass X-ray binaries (HMXBs) which are the relics of the short-lived upper end of the initial mass function.

ULTRA-DEEP HUBBLE SPACE TELESCOPE IMAGING OF THE SMALL MAGELLANIC CLOUD: THE INITIAL MASS FUNCTION OF STARS WITH M 1M to measure the IMF include modeling the luminosity functions of star-forming regions, young star clusters, and old clusters.

9 We refer to the initial mass function as the distribution of stellar masses. We determined the present-day mass functions (PDMFs) of the five intermediate-age star clusters Lindsay 1, Kron 3, NGCNGCand Lindsay 38 and the old star cluster NGC in the Small Magellanic Cloud (SMC) based on observations with the Hubble Space Telescope Advanced Camera for.

The stellar content in H II regions and young star clusters of the Magellanic Clouds (MC) was studied by using UBV CCD photometry.

The purposes of this study are threefold: to investigate the evolution of massive stars in the H II regions and young star cluster; to derive stellar luminosity functions and to determine the stellar initial mass functions; and to study the structural properties of.

We demonstrate that such a difference can arise from different mass-radius relationsfor the embedded-clusters. Aug 04,  · Magellanic Cloud Globular Clusters - posted in Deep Sky Observing: Im putting together a data base of all known globular clusters.

Let me tell you, after spending months on this, it is not as simple as you might think. I feel like those parents searching for a cure for some rare disease, all the information is out there, but no one has put it all together to come up with an answer.

What I am. We present structural parameters for the seven intermediate-age and old star clusters NGC, Lindsay1, Kron3, NGC, NGC, Lindsay38, and NGC in the Small Magellanic Cloud (SMC). We fit King profiles and Elson, Fall, and Freeman profiles to both surface-brightness and star-count data taken with the Advanced Camera for Surveys aboard the Cited by: Apr 04,  · Abstract.

Based on new observations with the Wide Field Camera 3 onboard the Hubble Space Telescope, we report the discovery of an extended main-sequence turn-off (eMSTO) in the intermediate-age star cluster NGC This is the second case of an eMSTO being identified in a star cluster belonging to the Small Magellanic Cloud (SMC), after NGC Cited by: 3.

We have carried out deep near-infrared imaging observations of the N/N star-forming region in the Large Magellanic Cloud. We observed an area of ~ arcmin 2 (~80, pc 2 at the distance of the LMC) in the J, H, and K s bands. The observations are deep enough to detect Herbig Ae/Be stars down to ~3 M ⊙ in the LMC.

We discovered a total of and candidate Herbig Ae/Be and OB. In addition, one can see data on other supernova remnants, such as the oxygen-rich ND, on the immense central star cluster R of 30 Doradus, and the contrasting star clusters of NGC and its unnamed neighbor. This image has been fairly popular, showing up in textbooks and even the occasional childrens' book.

Large Magellanic Cloud and Surrounding Structures is a result of collaboration with my observatory partner, Josep Drudis. The goal of this project was to emphasize the various supergiant shells, emission nebula, supernova remnants, Wolf-Rayet bubbles and new star formation surrounding the Large Magellanic Cloud (LMC).

The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri. The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution.
