by Ivan Adamin in
July-August 2013 (#1) As part of VS-COMPAS data-mining program, here are six new pulsating RR Lyrae variables with the presence of the Blazhko effect listed. The research result on these objects is submitted to the VSX catalog for the first time by the VS-COMPAS team members. Photometric data from publicly available surveys (NSVS, CRTS, ASAS) was used a a source for light curves.
Below each object is presented along with the resulting folded light curve and some notes, if any.
 VSX J092806.8+090728 in Leo by Alexandr Ditkovsky (VS-COMPAS) J-K = 0.23 |
 NSVS 10303225 in Leo by Alexandr Ditkovsky (VS-COMPAS) NSVS and ASAS-3 data are contaminated by 2MASS J10430453+0903402 V= 14.9, sep. 24". Data has been deblended. J-K= 0.23 |
 NSVS 13082928 in Leo by Alexandr Ditkovsky (VS-COMPAS) J-K = 0.238 |
 CSS_J130739.5+011029 in Virgo by Andrey Prokopovich, Ivan Adamin (VS-COMPAS) J-K = 0.2. Secondary period is 0.62179 |
 VSX J133154.0+300010 in Canes Venatici by Alexandr Ditkovsky (VS-COMPAS) |
 NSVS 10564788 in Bootes by Alexandr Ditkovsky (VS-COMPAS) J-K= 0.214 |
Here is a resulting table containing basic data about the presented variables.
