Photometric analysis of globular clusters using modified Richardson–Lucy algorithm—comparison with DAOPHOT

In this paper, we show the comparison tests of a standard DAOPHOT photometric algorithm with new WHIDE method based on Richardson–Lucy deconvolution for the case of globular stellar cluster cores where the overlapping signal from nearby brig...

TYC 1083-12-1 - an SB2 binary mimicking an exoplanetary candidate

TYC 1083-12-1 (sp. type F8V) was identified as a potential exoplanetary candidate in the data from a photometric survey with a 30-cm telescope. From the radial velocity observations of the star, we found that it is a double-lined binary with...

History of the Delta a photometric system

We review the invention of the Delta a photometric system, which provides an efficient method to detect magnetic chemically peculiar stars, but also some other groups such as emission-line or metal-weak objects. Besides the investigation of ...

Short-term variability of 10 trans-Neptunian objects

We present our latest results about the short-term variability of trans-Neptunian objects (TNOs). We performed broad-band CCD photometric observations using several telescopes in Spain and Chile. We present results based on three years of ob...

Delta a Photometric survey of the small magellanic cloud

The narrow-band delta a photometric system measures the flux depression at lambda 5200 angstrom by comparing the flux at the band centre to adjacent regions. It has been shown that virtually all peculiar stars with magnetic fields (mCPs) hav...
