Pre-solar grains from novae and "Born-again giants" (2024)
Book Chapter

We review the properties of dust formed during classical nova eruptions and the Very Late Thermal Pulses (VLTPs) that occur during the later stages of post-Asymptotic Giant Branch evolution of low-mass stars. In both cases, carbon and hydrocarbon dus... Read More about Pre-solar grains from novae and "Born-again giants".

Snowflakes in a Furnace: Formation of CO and Dust in a Recurrent Nova Eruption (2023)
Journal Article

We report the detection of carbon monoxide (CO) and dust, formed under hostile conditions, in recurrent nova V745 Sco about 8.7 days after its 2014 outburst. The formation of molecules or dust has not been recorded previously in the ejecta of a recur... Read More about Snowflakes in a Furnace: Formation of CO and Dust in a Recurrent Nova Eruption.

Infrared spectroscopy of the 2022 eruption of the recurrent nova U Sco (2023)
Journal Article

We present near-infrared spectroscopy of the 2022 eruption of the recurrent nova U Sco, over the period from 5.2 to 45.4 days after outburst. This is the most intensive infrared study of this nova. Our observations started early after the outburst an... Read More about Infrared spectroscopy of the 2022 eruption of the recurrent nova U Sco.

The recurrent nova V3890 Sgr: a near-infrared and optical study of the red giant component and its environment (2022)
Journal Article

We present an analysis of the red giant component of the recurrent nova V3890 Sgr, using data obtained before and after its 2019 eruption. Its effective temperature is Teff = 3050±200 K for log g = 0.7, although there are modest changes in Teff. Ther...

X-ray powder diffraction study of the stability of clathrate hydrates in the presence of salts with relevance to the Martian cryosphere (2018)
Journal Article

Water on the present day Martian surface is thought to exist in two thermally distinct sub-surface reservoirs: as ice in the cryosphere and as groundwater located deeper in the crust. These sub-surface environments are thought to contain saline, rath...
