Century Dictionary and Cyclopedia
    • n pyx In the Roman Catholic Church, the vase or vessel in which the reserved eucharist is kept. The name pyx (pyxis) for this vessel seems to have come into use in the ninth century. In earlier times the reserved sacrament was kept in an arca, columba, or turris (see reservation). In the Greek Church the vessel in which the sacrament is reserved is called the artophorion, pyxion, or pyxis. The pyx has also been used for unconsecrated altar-breads. It has generally been made cylindrical in shape, with a foot like that of a chalice, and has sometimes had a conical cover. In modern usage it is much smaller than formerly, and is often made round and flat like a watch-case, for convenience, especially in carrying the sacrament to the sick. For public exposition of the sacrament a monstrance or ostensory is used instead.
    • n pyx A box or chest in which specimen coins are deposited at the British mint.
    • n pyx Nautical, the metallic box in which the nautical compass-card is suspended.
    • n pyx In anatomy, the acetabulum of the hip-bone; the cotyloid cavity; the pyxis.

In science:

T Pyx the orbital period is Porb = 1.83 hours, the ejected shell mass is Mshell , and the mass of the companion star is Mcomp = 0.12 M⊙ (Selvelli et al. 2008; Knigge et al. 2000).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
So V1500 Cyg appears to be similar to T Pyx in having an ordinary nova eruption in a short-period system inducing a brightbut-fading supersoft source that powers a sudden jump in the accretion rate.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
V1500 Cyg has substantially different properties from T Pyx, with it being a polar and having MW D ∼ 1.15 M⊙ (Hachisu & Kato 2006).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
But again, other aspects of V723 Cas are different from T Pyx, e.g., the orbital period is 16.6 hours (Goranskij et al. 2007) and the ejected material is neon-rich (Iijima 2006).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
RW UMi is like T Pyx in a number of other ways: it has a very short orbital period of 1.42 hours (Retter & Lipkin 2001), it is slowly declining in optical brightness at the rate of 0.02 mag yr−1 (Bianchini et al. 2003), and it has a nova shell (Cohen 1985; Esenoglu et al. 2000).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
But RW UMi is different from T Pyx in that it is likely an intermediate polar (Bianchini et al. 2003).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
We now have seven examples of novae that behaved like T Pyx in that the quiescent brightness (and thus the accretion rate) increased by a large factor across a classical nova event.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
The brightness increase of T Pyx has solid precedent, and the cause is apparently due to the initiation of a long-lasting supersoft source (Schaefer & Collazzi 2009).
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
Anupama (2002), Hachisu et al. (2008), and Livio & Truran (1992) all conclude that T Pyx will become a Type Ia supernova, always based on the general consideration that the WD is near the Chandrasekhar mass and accreting material at a high rate.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
But these papers are either not particular to T Pyx or are without detailed calculations.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
Knigge et al. (2000) considered that T Pyx might become a supernova, provided that the combined mass of the two stars is above the Chandrasekhar limit.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
Selvelli et al. (2008) concluded that T Pyx would not become a supernova, with the primary reason being their estimates of a high ejected mass and an accreted mass that could not be anywhere near as large, so the white dwarf could not be gaining mass.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
A good indication that T Pyx cannot become a supernova is simply that it does not have the required total mass.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
Even if theory is wrong, and, say, half the accreted material is retained by the WD, then T Pyx can become a supernova only if the WD is within 0.06 M⊙ of the limit, and this does not seem likely given the results from Section 7.3.
The Nova Shell and Evolution of the Recurrent Nova T Pyxidis
With this, we already know that there is little real chance of T Pyx ever collapsing as a supernova.
