Variables

Light curves of some new-found variables. My data (gathered with DSLR) were transformed to Johnson V (Johnson B) system using an approach described in The AAVSO DSLR Observing Manual (standard transformation) or the "VSF" (synthetic V-filter) approach [R. Pieri] in some cases.

PMAK V1

PMAK V1 (VSX)

Type: EW; Period= 0.40280 d

Range: 13.10 - 13.38 V


Note: initial epoch differs from those specified in the VSX by half of the period (it is hard to distinguish between the primary and the secondary minimum)

PMAK V3

PMAK V3 (VSX)

Type: SRS

Range: 12.8 - 13.4 V


PMAK V4

PMAK V4 (VSX)

Type: SRB

Range: 12.6 - 13.1 V


PMAK V5

PMAK V5 (VSX)

Type: EA

Range: 13.15 - 13.6: V


Note 1: Magnitudes contaminated by 2MASS J21301793+3510301 (V= 14.5; sep. 5”), range has been corrected.

Note 2: Transformation from DSLR TG to Johnson V was done using VSF approach [R. Pieri]

Note 3: Period differs slightly from that specified in the VSX, it was recalculated.

PMAK V6

PMAK V6 (VSX)

Type: RS

Range: 11.96 - 12.25 V


PMAK V7

PMAK V7 (VSX)

Type: SRB

Range: 10.9 - 11.4 V


PMAK V9

PMAK V9 (VSX)

Type: SRD

Range: 8.9 - 9.3 V


PMAK V15

PMAK V15 (VSX)

Type: SRB

Range: 9.7 - 10.15 V


PMAK V16

PMAK V16 (VSX)

Type: ELL

Range: 10.86 - 10.93 V


PMAK V26

PMAK V26 (VSX)

Type: EA

Range: 11.94 - 12.03 V


PMAK V31

PMAK V31 (VSX)

Type: BY

Range: 13.15 - 13.48 V
