This discovery, made by NASA\u2019s <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/\" rel=\"noopener\">Hubble Space Telescope<\/a>\u2019s sensitive ultraviolet observations, suggests these rare white dwarfs may be more common than previously suspected.<\/p>\n<p>\u201cIt\u2019s a discovery that underlines things may be different from what they appear to us at first glance,\u201d said the principal investigator of the Hubble program, Boris Gaensicke, of the University of Warwick in the United Kingdom. \u201cUntil now, this appeared as a normal white dwarf, but Hubble\u2019s ultraviolet vision revealed that it had a very different history from what we would have guessed.\u201d<\/p>\n<p>A white dwarf is a dense object with the same diameter as Earth, and represents the end state for stars that are not massive enough to explode as core-collapse supernovae. Our Sun will become a white dwarf in about 5 billion years.\u00a0<\/p>\n<p>In theory, a white dwarf can have a mass of up to 1.4 times that of the Sun, but white dwarfs heavier than the Sun are rare. These objects, which astronomers call ultra-massive white dwarfs, can form either through the evolution of a single massive star or through the merger of a white dwarf with another star, such as a binary companion.\u00a0<\/p>\n<p>This new discovery, published in the journal <a href=\"https:\/\/www.nature.com\/articles\/s41550-025-02590-y\" rel=\"noopener\">Nature Astronomy<\/a>, marks the first time that a white dwarf born from colliding stars has been identified by its ultraviolet <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/multimedia\/hubble-glossary\/#h-spectrum\" rel=\"noopener\">spectrum<\/a>. Prior to this study, six white dwarf merger products were discovered via carbon lines in their visible-light spectra. \u00a0All seven of these are part of a larger group that were found to be bluer than expected for their masses and ages from <a href=\"https:\/\/www.esa.int\/Science_Exploration\/Space_Science\/Gaia\/Gaia_reveals_how_Sun-like_stars_turn_solid_after_their_demise\" rel=\"noopener\">a study with ESA\u2019s Gaia mission in 2019<\/a>, with the evidence of mergers providing new insights into their formation history.<\/p>\n<p>Astronomers used Hubble\u2019s <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/observatory\/design\/cosmic-origins-spectrograph\/\" rel=\"noopener\">Cosmic Origins Spectrograph<\/a> to investigate a white dwarf called WD 0525+526. Located 128 light-years away, it is 20% more massive than the Sun. In visible light, the spectrum of WD 0525+526\u2019s atmosphere resembled that of a typical white dwarf. However, Hubble\u2019s ultraviolet spectrum revealed something unusual: evidence of carbon in the white dwarf\u2019s atmosphere.\u00a0<\/p>\n<p>White dwarfs that form through the evolution of a single star have atmospheres composed of hydrogen and helium. The core of the white dwarf is typically composed mostly of carbon and oxygen or oxygen and neon, but a thick atmosphere usually prevents these elements from appearing in the white dwarf\u2019s spectrum.\u00a0<\/p>\n<p>When carbon appears in the spectrum of a white dwarf, it can signal a more violent origin than the typical single-star scenario: the collision of two white dwarfs, or of a white dwarf and a subgiant star. Such a collision can burn away the hydrogen and helium atmospheres of the colliding stars, leaving behind a scant layer of hydrogen and helium around the merger remnant that allows carbon from the white dwarf\u2019s core to float upward, where it can be detected. \u00a0<\/p>\n<figure class=\"wp-block-embed alignwide is-type-video is-provider-youtube wp-block-embed-youtube\">\n<div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Hubble Uncovers Star\u2019s Unusual Atmosphere\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/nyWuLSIoosk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div>\n<\/figure>\n<p>WD 0525+526 is remarkable even within the small group of white dwarfs known to be the product of merging stars. With a temperature of almost 21,000 kelvins (37,000 degrees Fahrenheit) and a mass of 1.2 solar masses, WD 0525+526 is hotter and more massive than the other white dwarfs in this group.<\/p>\n<p>WD 0525+526\u2019s extreme temperature posed something of a mystery for the team. For cooler white dwarfs, such as the six previously discovered merger products, a process called convection can mix carbon into the thin hydrogen-helium atmosphere. WD 0525+526 is too hot for convection to take place, however. Instead, the team determined a more subtle process called semi-convection brings a small amount of carbon up into WD 0525+526\u2019s atmosphere. WD 0525+526 has the smallest amount of atmospheric carbon of any white dwarf known to result from a merger, about 100,000 times less than other merger remnants.<\/p>\n<p>The high temperature and low carbon abundance mean that identifying this white dwarf as the product of a merger would have been impossible without Hubble\u2019s sensitivity to ultraviolet light. Spectral lines from elements heavier than helium, like carbon, become fainter at visible wavelengths for hotter white dwarfs, but these spectral signals remain bright in the ultraviolet, where Hubble is uniquely positioned to spot them.<\/p>\n<p>\u201cHubble\u2019s Cosmic Origins Spectrograph is the only instrument that can obtain the superb quality ultraviolet spectroscopy that was required to detect the carbon in the atmosphere of this white dwarf,\u201d said study lead Snehalata Sahu from the University of Warwick.<\/p>\n<p>Because WD 0525+526\u2019s origin was revealed only once astronomers glimpsed its ultraviolet spectrum, it\u2019s likely that other seemingly \u201cnormal\u201d white dwarfs are actually the result of cosmic collisions \u2014 a possibility the team is excited to explore in the future.<\/p>\n<p>\u201cWe would like to extend our research on this topic by exploring how common carbon white dwarfs are among similar white dwarfs, and how many stellar mergers are hiding among the normal white dwarf family,\u201d said study co-leader Antoine Bedrad from the University of Warwick. \u201cThat will be an important contribution to our understanding of white dwarf binaries, and the pathways to supernova explosions.\u201d<\/p>\n<p><em>The Hubble Space Telescope has been operating for more than three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe.
