败臼增一

敗臼增一 （南魚座β）在星表上是南天星座，南魚座內的一對聯星。它的視星等為肉眼可見的4.29等。依據從地球觀察得到的年周視差22.84mas，這顆恆星與太陽的距離是143光年。它的座標位置是X射線的發射源，亮度為7021884999999999999♠88.5×1020 W，但這應該不是來自這顆A-型恆星，可能還有其它發射源。 Oblak（1978年）曾將其視為一顆三合星，但隨後就將其列為聯星。它的星等為4.29，主星A，是一顆白色的A型主序星，類型為 A1V。估計質量是2.3太陽質量，半徑是2.1太陽半徑。有效溫度是9,638K，來自光球層的發光強度是太陽亮度的37倍。紅外過量的證據顯示它有岩屑盤，估計其軌道距離主星12AU，溫度為188K。伴星B的星等為7.8，恆星分類為A2V，與主星距離30.3角秒。 敗臼增一相對於太陽以每秒14.4公里的速度在銀河系中移動。它投射的銀河軌道讓它在距離銀河中心23,900至28,300光年的軌道上運動。[來源可靠？] 在中國，它與敗臼一（天鶴座γ）、敗臼二、敗臼三和敗臼四（英语：19 Piscis Austrini）組成星官敗臼。 van Leeuwen, F., Validation of the new Hipparcos reduction, Astronomy and Astrophysics, 2007, 474 (2): 653–664, Bibcode:2007A&A...474..653V, arXiv:0708.1752 , doi:10.1051/0004-6361:20078357.  Nicolet, B., Photoelectric photometric Catalogue of homogeneous measurements in the UBV System, Astronomy and Astrophysics Supplement Series, 1978, 34: 1–49, Bibcode:1978A&AS...34....1N.  Oblak, E., uvbybeta photometry of wide visual double stars with B, A and F spectral type - I., Astronomy and Astrophysics Supplement Series, December 1978, 34: 453–475, Bibcode:1978A&AS...34..453O.  Royer, F.; et al, Rotational velocities of A-type stars.
