Explanation:

An international team has reported a unique phenomenon in a white dwarf about 1,400 light years from Earth. They saw the white dwarf lose its brightness in 30 minutes.

• These gaps in brightness have been previously reported but the process usually takes place over a period of several days to months.
• The team observed the phenomena using NASA’s Transiting Exoplanet Survey Satellite (TESS).
• The white dwarf is part of a binary system called TW Pictoris, where a star and a white dwarf orbit each other.
• The two objects are so close to each other that the star transfers material to the white dwarf.
• As this material approaches the white dwarf it forms an accretion disk or a disk of gas, plasma, and other particles around it. TW Pictoris is located in the Pictoris constellation, and the binary system is about 1400 light years from us.
• The team notes that a process called magnetic gating may be at play. This happens when the magnetic field is spinning so rapidly it creates a barrier disrupting the amount of food the white dwarf can receive.
• The team hopes that this discovery will help us understand the physics behind accretion – how black holes and neutron stars feed material from their nearby stars.
• A typical white dwarf is half the size of our Sun and has a surface gravity 100,000 times that of Earth. Using the Hubble Space telescope and Transiting Exoplanet Survey Satellite (TESS), astronomers have identified several white dwarfs over the years.

Hence both statements are correct.
