The Star Cluster population of NGC 5253 ⋆
We present a detailed analysis of the star cluster population in the starburst galaxy NGC 5253. Our work is based on HST optical and VLT Ks images. We detect more than 300 clusters, and for all of them we derive the photometry in the V, I and Ks bands and built a color-color V-I/V-Ks diagram. After correction for star contamination, we matched 115 sources in all the three bands V, I and Ks. Com...
متن کاملThe Birth of a Super Star Cluster : NGC 5253
We present images of the 7mm free-free emission from the radio “supernebula” in NGC 5253 made with the Very Large Array and the Pie Town link. The images reveal structure in the nebula, which has a≤ 1 pc (∼50 mas radius) core requiring the excitation of 1200 O7 stars. The nebula is elongated, with an arc of emission curving to the northeast and to the south. The total ionizing flux within the c...
متن کاملDust and Super Star Clusters in NGC 5253
We present new observations of the famous starburst galaxy NGC 5253 which owes its celebrity to possibly being the youngest and closest starburst galaxy known. Our observations in the infrared and millimeter contribute to shed light on the properties of this interesting object. We have used our new data along with data from the literature to study the properties of the young stellar clusters pr...
متن کاملHigh spatial resolution mid - infrared spectroscopy of NGC 5253 : The stellar content of the embedded super - star cluster ⋆
We present the N-band (8–13 µm) spectrum of the hidden compact radio super-star cluster in NGC 5253, C2, obtained with TIMMI2 on the ESO 3.6 m telescope. The spectrum is characterised by a rising continuum due to warm dust, a silicate absorption and a strong [S ] line at 10.5 µm. Weaker lines of [Ar ] at 9.0 µm and [Ne ] at 12.8 µm are also present. The continuum can be modeled by an opt...
متن کاملPhotometric study of the variable star population in the globular cluster NGC 6397
We present the results of a photometric survey for variable stars in the central region of the nearby globular cluster NGC 6397. Time series photometry was obtained for 30 variable objects. The sample includes 12 new objects, of which 6 show periodic light curves and 2 are eclipsing binaries of unknown period. Six variables possess certain and three possess likely X-ray counterparts detected wi...
