TW Pictoris

TW Pictoris

TW Pictoris is a star based on the spectral type that was recorded in Simbad at Strasbourg University about 1400 Light Years away from Earth. It is not part of the Pictor Constellation outline. But it is within the borders of the Constellation. It consists of a White Dwarf, that feeds from a surrounding accretion disk, fueled by Hydrogen and Helium from its smaller companion star. As the White Dwarf accretes it becomes brighter.

Studies on TW Pictoris

Scientists studied about TW Pictoris using data from the NASA’s Transiting Exoplanet Survey Satellite (TESS). The studies revealed that the White Dwarf star in the Binary Star System is brightening and then dropping abruptly. The Astronomer Simone Scaringi and colleagues at Durham University saw the White Dwarf in TW Pictoris lose brightness in 30 minutes. It is a process previously seen only to occur in accreting White Dwarfs over a period of several daya to months. It is believed that this is due to the magnetic fields. These interactions are known as Symbiotic Stars and through their more romantic name Vampire Star.

Location of TW Pictoris

The Location of a star in the night sky is determined by the Right Ascension (RA) and Declination (Dec). RA and Dec are equivalent to the Longitude and Latitude on Earth. The Right Ascension expressed in time (hh:mm:ss) is how far the star is along the Celestial Equator. If RA is positive then it is Eastward. The Declination is compared to the Celestial Equator (how far North or South the object is) and is expressed in degrees. The location of TW Pictoris is 05 34 50.5864710889 and -58 01 40.767221479.
