First planetesimals from DESI DR1: 12 highly metal-rich white dwarfs

Paula Izquierdo, Andrew Swan, Boris T. Gänsicke +43

Metal-enriched white dwarfs provide a unique insight into the composition of exoplanet interiors. These stars accrete the debris of disrupted planetary bodies, and hence, measuring…

I Can Do It With A Broken Planetesimal: Characterising the planetary debris in heavily polluted cool white dwarfs

Anna-Maria Cutolo, Boris T. Gänsicke, Andrew Swan +7

We present the analysis of four cool and strongly metal-polluted H-atmosphere white dwarfs observed with X-shooter. We compared their atmospheric parameters obtained from spectrosc…

NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

White dwarf planetary systems in the ultraviolet

Jamie Williams, Amy Bonsor, Boris Gänsicke +9

Almost every known planet host will evolve into a white dwarf, and the surviving planetary material will continue to orbit this stellar remnant. Asteroids perturbed onto star-grazi…

From Hubble to HWO: Bridging the Frontier of White Dwarf Exoplanet Science

Laura K. Rogers, Siyi Xu, Martin Barstow +20

White dwarf stars, the endpoint of stellar evolution for 97% of stars in our Milky Way, offer a unique and powerful window into the bulk elemental composition of rocky exoplanetary…

Discovery of an icy and nitrogen-rich extrasolar planetesimal

Snehalata Sahu, Boris T. Gänsicke, Jamie T. Williams +7

White dwarfs accreting planetary debris provide detailed insight into the bulk composition of rocky exo-planetesimals. However, only one Kuiper-Belt analogue has been identified in…

Measurements of three exo-planetesimal compositions: a planetary core, a chondritic body, and an icy Kuiper belt analogue

Jamie T. Williams, Boris T. Gänsicke, Snehalata Sahu +6

The study of planetesimal debris accreted by white dwarfs offers unique insights into the composition of exoplanets. Using far-ultraviolet and optical spectroscopy, we have analyse…

An observational overview of white dwarf stars

Ingrid Pelisoli, Jamie Williams

White dwarf stars are the most common final stage of stellar evolution. Since the serendipitous discovery of the first white dwarf by William Herschel and the first physical models…
