摘要

我们在捷克共和国Klášterec nad Ohří附近的Horní Halže上报道了在仙后座星座中发现的四颗新的变星，这些变星是由TOPTEC团队操作的HALZ望远镜的档案。这三颗恒星的编号分别为UCAC4 718-108144(23小时04米16.383秒+53°29′44.78”)、UCAC4 725-101725(23小时09米27.87秒+54°51′23.27”)、UCAC4 725-101699(23小时09米19.53秒+54°57′57.18”)、UCAC4 722-105015(23小时10米424秒+54°14′33.33”)。从光度曲线上看，这些恒星应该是HADS型(UCAC4 718-108144)、EW型(UCAC4 725-101725)、EA型(UCAC4 725-101699)和ELL型(UCAC4 722-105015)。我们在CzeV星表中将这些恒星登记为新变星CzeV709、CzeV710、CzeV711和CzeV715。

Four new variable stars in Cassiopea discovered with DSLR camera

We report on the discovery of new four variable stars in the Cassiopea constellation from the archive of the HALZ telescope, operated by the TOPTEC team at Horní Halže, near Klášterec nad Ohří, Czech Republic. The stars are catalogued as UCAC4 718-108144 (23h 04m 16.383s +53° 29’ 44.78”), UCAC4 725-101725 (23h 09m 27.87s +54° 51’ 23.27”), UCAC4 725-101699 (23h 09m 19.53s +54° 57’ 57.18”), UCAC4 722-105015 (23h 10m 42.4s +54° 14’ 33.33”). From the light curve, the stars should be a HADS – type variable (UCAC4 718-108144), an EW – type variable (UCAC4 725-101725), an EA - type variable (UCAC4 725-101699) and an ELL – type variable (UCAC4 722-105015). We registered these stars in the CzeV catalogue as new variable stars CzeV709, CzeV710, CzeV711 and CzeV715.
