In December 1988, American astrophysicists Benjamin Zuckerman and Eric Becklin detected a substantial circumstellar disc encircling the white dwarf star G 29-38, stemming from a near-infrared survey of 200 white dwarfs.[[http://adsabs.harvard.edu/abs/1988Natur.336..656B A low-temperature companion to a white dwarf star], E. E. Becklin & B. Zuckerman, Nature 336 (Dec. 15, 1988), pp. 656-658] Zuckerman and Becklin conducted further investigations on the white dwarf star, uncovering that the circumstellar disc emits notable radiation within the 2 to 5 micrometer range. This discovery suggests potential interactions between exoasteroids and radiant matter, possibly leading to their ejection into space.[[http://adsabs.harvard.edu/abs/1987Natur.330..138Z Excess infrared radiation from a white dwarf - an orbiting brown dwarf?] B. Zuckerman & E. E. Becklin, Nature 330, (Nov. 12, 1987), pp. 138-140] Subsequent observations in 2004 by the Spitzer Space Telescope revealed the presence of a dust cloud surrounding G 29-38. This phenomenon is believed to have originated from the disintegration of an exocomet or exoasteroid as it interacted with the white dwarf.[[http://adsabs.harvard.edu/abs/2005ApJ...635L.161R The Dust Cloud around the White Dwarf G29-38], William T. Reach, Marc J. Kuchner, Ted von Hippel, Adam Burrows, Fergal Mullally, Mukremin Kilic, and D. E. Winget, Astrophysical Journal 635, #2 (December 2005), pp. L161–L164.]
In May 2023, the James Webb Space Telescope provided images of Fomalhaut,[{{cite web |date=8 May 2023 |title=Webb Looks for Fomalhaut's Asteroid Belt and Finds Much More |url=https://www.nasa.gov/missions/webb/webb-looks-for-fomalhauts-asteroid-belt-and-finds-much-more/ |access-date=30 December 2023 |website=nasa.gov}}] a young star positioned 25 light-years (ly) away from Earth. Scientists analyzed these images and conducted simulations and tests on Fomalhaut's asteroid belt, proposing that it likely formed due to collisions involving larger celestial bodies.
Another notable star hosting an asteroid belt is the white dwarf star WD 0145+234. It is hypothesized that WD 0145+234 once hosted an exoasteroid or exoplanet in orbit around it, which was disrupted, leading to the formation of a substantial exoasteroid belt. Due to the star's dimensions, scientists infer that the accretion disk surrounding WD 0145+234 is highly active, resulting in the regular disruption of exoasteroids by the star's gravitational pull. In 2018, astronomers observed a 10% increase in the star's mid-infrared light, indicative of the recent destruction of an exoasteroid, which led to the formation of a cloud of metallic dust partially obscuring WD 0145+234 from Earth's view.[{{cite web |last1=Letzter |first1=Rafi |date=17 October 2019 |title=An Asteroid-Smashing Star Ground a Giant Rock to Bits and Covered Itself in the Remains |url=https://www.livescience.com/white-dwarf-asteroid-smasher.html |access-date=31 December 2023 |website=livescience.com}}]
