Detecting stars in crowded stellar fields
نویسنده
چکیده
A comparison is made between some conventional and new methods for detecting stars in crowded stellar images. The new methods are (1) Lucy-Richardson deconvolution of the image before detection, and (2) fitting the Point Spread Function to each pixel in the image. These methods are applied to both a synthetic image and a real one. The deconvolution method looks very promising, and gives better results than the conventional ones, provided a large number of iterations are applied.

Crowded - field photometry from HST - imaging ⋆
We present a thorough investigation of stellar photometry based on HST imaging of crowded fields at 85 and 10 from the centre of the high-surface brightness elliptical galaxy M32. The Principal Investigators of the present archive data have elsewhere presented an impressive colour-magnitude diagram of the field at 85. Based on the same data we enlarge on their photometric analysis and supplemen...
متن کاملProbabilistic Catalogs for Crowded Stellar Fields
We introduce a probabilistic (Bayesian) method for producing catalogs from images of crowded stellar fields. The method is capable of inferring the number of sources N in the image and can also handle the challenges introduced by overlapping sources. The luminosity function of the stars can also be inferred even when the precise luminosity of each star is uncertain. This is in contrast with sta...
متن کاملDetection of point sources
Photometry of individual sources requires an initial phase of detection. The detection process can be separated into two phases: (1) preprocessing of the image, and (2) actual detection, yielding a list of discrete sources. Given a distribution of background intensities, the probabilityof intensitydeviations for light sources as a result of the background can be calculated. Setting a maximum ac...
متن کاملTHE EFFECT OF COSMIONS ON THE STABILITY OF MAIN SEQUENCE STELLAR CORES
We have studied the effect of hypothetical Cosmions on the core stability of main sequence stars (of populations I and II). Cosmions, with a mass of 4-10 Gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. Raby [17] showed the existence of a local thermal instability caused by the presence of Cosmions in the sol...
متن کاملPhotometric biases due to stellar blending: implications for measuring distances, constraining binarity and detecting exoplanetary transits
We investigate blending, binarity and photometric biases in crowded-field CCD imaging. For this, we consider random blend losses, which correspond to the total number of stars left undetected in unresolved blends. We present a simple formula to estimate blend losses, which can be converted to apparent magnitude biases using the luminosity function of the analyzed sample. Because of the used ass...
