Abstract:
We present the first detailed investigation of six eclipsing binary
systems in the TESS field. The TESS light curves of the targets are
analysed by determining the initial effective temperatures via SED
fits. The absolute parameters are derived and the systems are compared
to well-known binaries of the same type. Results show that CD-58 791,
CD-62 1257 and TYC 9356-355-1 are detached binary systems. CD-54 942
and UCAC4 136-007295 are contact binaries while TYC 8508-1413-1 is a
semidetached system.
Description:
Times of minimum light of CD54 942, CD-58 791, CD-62 1257, TYC
8508-1413-1, TYC 9356-355-1 and UCAC4 136-007295 as derived from the
TESS light curves are listed. TYC 8508, TYC 9356 and UCAC4 136 refer
to TYC 8508-1413-1, TYC 9356-355-1 and UCAC4 136-007295, respectively.
