A multicolour CCD photometric and mass function study of the distant southern open star clusters NGC 3105, NGC 3603, Melotte 105, Hogg 15, NGC 4815, Pismis 20 and NGC 6253

Sagar, R; Munari, U; de Boer, K. S (Royal Astronomical Society, 2001-10)

We derive cluster parameters and mass functions from new UBVRI CCD photometric observations of ~3500 stars reaching down to V~20mag for the distant southern open star clusters NGC 3105, NGC 3603, Melotte 105, Hogg 15, NGC ...
Optical photometry and basic parameters of 10 unstudied open clusters

Subramaniam, A; Carraro, G; Janes, K. A (Blackwell Publishing, 2010-05)

We present BVI CCD photometry of 10 northern open clusters, Berkeley43, Berkeley45, Berkeley47, NGC 6846, Berkeley49, Berkeley51, Berkeley89, Berkeley91, Tombaugh4 and Berkeley9, and estimate their fundamental parameters. ...
RACE-OC project: rotation and variability in the open cluster M 11 (NGC 6705)

Messina, S; Parihar, P. S; Koo, J. R; Kim, S. L; Rey, S. C; Lee, C. U (EDP Sciences, 2010-04)

Rotation and magnetic activity are intimately linked in main-sequence stars of G or later spectral types. The presence and level of magnetic activity depend on stellar rotation, and rotation itself is strongly influenced ...
