We have obtained near-infrared (0.80–2.45 $\, \mu$m) spectra of the recurrent nova LMCN 1968-12a on two occasions during its 2024 August eruption. This is the first near-infrared spectroscopy of an extragalactic nova. The initial spectrum, on day 8.4... Read More about Near-infrared spectroscopy of the LMC recurrent nova LMCN 1968-12a.

Pre-solar grains from novae and "Born-again giants" (2024)
Book Chapter
Evans, A., & Gehrz, R. (2024). Pre-solar grains from novae and "Born-again giants". In Presolar grains in extra-terrestrial materials. Elsevier

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".

A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii (2024)
Journal Article

A near-infrared spectrum of nova V1716 Scorpii (PNV J17224490-4137160), a recent bright ( Vmax=7.3 mag), Fermi-LAT detected γ-ray source, was modeled using the photoionization code CLOUDY. Abundances were estimated for He, C, N, O, Si, Al, Mg, Fe, Ne... Read More about A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii.

A dusty rain falls on the nova V959 Monocerotis (2024)
Journal Article
Evans, A., Banerjee, D. P. K., Varricatt, W. P., & Joshi, V. (2024). A dusty rain falls on the nova V959 Monocerotis. Monthly Notices of the Royal Astronomical Society, 531(1), 728-738. https://doi.org/10.1093/mnras/stae1240

We present archival and ground-based infrared observations of the γ-ray-emitting nova V959 Mon, covering the period 100–4205 d after the 2012 eruption. We use these data to determine that the secondary in the nova system is a G5 main sequence star. D... Read More about A dusty rain falls on the nova V959 Monocerotis.
