- 2MASS J05325346+8246465 (abbreviated 2MASS J0532+8246) is possibly the first brown dwarf observed in the galactic halo of the Milky Way, and the first known substellar subdwarf star. It was discovered from Two Micron All-Sky Survey data, and verified by observations at Palomar Observatory and W. M. Keck Observatory. It has a low metallicity, which indicates it is an old star. The mass and temperature of 2MASS 0532+8246 makes it a rare object in stellar-substellar gap between conventional stars and brown dwarfs. It produces roughly half of its luminosity from hydrogen fusion. Such "gap" objects, covering a narrow range of masses but a wide range of temperatures, and powered by unsteady hydrogen fusion, are exotic but expected to be more common among low-metallicity objects like 2MASS J05325346+8246465.

- 2MASS J05325346+8246465, auch abgekürzt als 2MASS 0532+8246 bezeichnet, ist ein möglicher L-Unterzwerg im Sternbild Giraffe. Modellenrechnungen ergeben starke Hinweise, dass es sich um ein substellares Objekt unmittelbar unterhalb der Massengrenze für das Wasserstoffbrennen handelt. (de)
- 2MASS J05325346+8246465는 최초로 발견된 이자 준왜성이다. 현재 수명은 10-15억 년이다. (ko)
- 2MASS 0532+8246 – brązowy karzeł leżący w gwiazdozbiorze Żyrafy. Należy do typu widmowego sdL7. Jego masa wynosi mniej niż 0,1 masy Słońca, a metaliczność (zawartość pierwiastków cięższych niż hel) zaledwie 0,1 do 0,01 metaliczności Słońca. (pl)
