  Compactness of some stars is explained if they are strange stars (SS) as
shown by Dey et al. (1998) (D98) and Li et al. (1999a). One of these compact
star candidates is the SAX J1808.4-3658 (SAX in short) believed to be an
important link in the genesis of radio pulsars. SS have also been suggested for
bursting X-ray pulsars (GRO J1744-28, Cheng et al. 1998), from quasi-periodic
oscillations (QPO) of X-ray binaries (4U 1728-34, Li et al. 1999b) and from
peculiarity of properties of radio pulsars (PSR 0943+10, Xu et al.1999; Kapoor
et al. 2000). We now extend the calculation to include high temperatures upto T
= 70 MeV ~ 8 times 10^{11} ^oK and find that the nature of the mass (M) and
radius (R), derived from astrophysical data, is still retained. The entropy is
calculated and matches onto that calculated from hadronic models thus
supporting the idea that the quark-hadron transition may be continuous.
