The results of CCD photometric survey performed with the 90/180 cm Schmidt-Cassegrain Telescope of the Nicolaus Copernicus University Astronomical Observatory in Piwnice (Poland) a…
A Planetary Mass Companion to the K0 Giant HD 17092
A. Niedzielski, M. Konacki, A. Wolszczan +6
We report the discovery of a substellar-mass companion to the K0-giant HD 17092 with the Hobby-Eberly Telescope. In the absence of any correlation of the observed 360-day periodici…
CCD BV survey of 42 open clusters
G. Maciejewski, A. Niedzielski
We present results of a photometric survey whose aim was to derive structural and astrophysical parameters for 42 open clusters. While our sample is definitively not representative…
