Hungry white dwarfs: Solving the mystery of metal contamination in stars that were supposed to contain only light elements

White dwarfs make up the vast majority of stars in the galaxy. When they were used they did not reach the stage of producing heavy substances, so how did these substances reach them after their death?

An artist's impression of the large-scale landscape of FU~Ori. The image shows the currents created by the interaction between strong stellar winds triggered by the outburst and the remnant mantle from which the star formed. The stellar wind drives the shock wave into the mantle and the CO gas carried away by the shock is the new discovery of the ALMA observatory. Credit: NSF/NRAO/S. Dagnello

Space and astronomy

Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.
