V1388 Ori is an early-B type detached eclipsing binary whose physical properties have previously been measured from dedicated spectroscopy and a ground-based survey light curve. We reconsider the properties of the system using newly-available light c... Read More about REDISCUSSION OF ECLIPSING BINARIES. PAPER 10: THE PULSATING B-TYPE SYSTEM V1388 ORIONIS.

Stringent limits on 28SiO maser emission from the recurrent nova T Coronae Borealis (2022)
Journal Article
(2022). Stringent limits on 28SiO maser emission from the recurrent nova T Coronae Borealis. Monthly Notices of the Royal Astronomical Society, 4894-4897. https://doi.org/10.1093/mnras/stac1589

There are indications that the third known eruption of the recurrent nova T CrB is imminent, and multi-wavelength observations prior to the eruption are important to characterise the system before it erupts. T CrB is known to display the SiO fundamen... Read More about Stringent limits on 28SiO maser emission from the recurrent nova T Coronae Borealis.

Monthly Notices of the Royal Astronomical Society, 515(4), 6046-6065. https://doi.org/10.1093/mnras/stac2096

Following the discovery of SAGE0536AGN (z ∼ 0.14), with the strongest 10-μm silicate emission ever observed for an active galactic nucleus (AGN), we discovered SAGE0534AGN (z ∼ 1.01), a similar AGN but with less extreme silicate emission. Both were o... Read More about The VMC survey - XLIX. Discovery of a population of quasars dominated by nuclear dust emission behind the Magellanic Clouds.

The study of pulsating stars in eclipsing binaries holds the promise of combining two different ways of measuring the physical properties of a star to obtain improved constraints on stellar theory. Gravity (g) mode pulsations such as those found in γ... Read More about Four bright eclipsing binaries with γ Doradus pulsating components: CM Lac, MZ Lac, RX Dra, and V2077 Cyg.

Breast calcification micromorphology classification (2022)
Journal Article

Objectives: The importance of consistent terminology in describing the appearance of breast calcifications in mammography is well recognised. Imaging of calcifications using electron microscopy is a globally growing field of research. We therefore su... Read More about Breast calcification micromorphology classification.

Realistic 3D hydrodynamics simulations find significant turbulent entrainment in massive stars (2022)
Journal Article
Rizzuti, F., Hirschi, R., Georgy, C., Arnett, W. D., Meakin, C., & Murphy, A. S. (2022). Realistic 3D hydrodynamics simulations find significant turbulent entrainment in massive stars. Monthly Notices of the Royal Astronomical Society, 515(3), 4013-4019. https://doi.org/10.1093/mnras/stac1981

Our understanding of stellar structure and evolution coming from one-dimensional (1D) stellar models is limited by uncertainties related to multidimensional processes taking place in stellar interiors. 1D models, however, can now be tested and improv...

Context. Brown dwarfs are transition objects between stars and planets that are still poorly understood, for which several competing mechanisms have been proposed to describe their formation. Mass measurements are generally difficult to carry out for...

HATS-18 b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We present extensive photometry of HATS-18 from which we measure 27 times of... Read More about A search for transit timing variations in the HATS-18 planetary system.

Quantifying kinematic substructure in star-forming regions with statistical tests of spatial autocorrelation (2022)
Journal Article

We investigate whether spatial-kinematic substructure in young star-forming regions can be quantified using Moran's $I$ statistic. Its presence in young star clusters would provide an indication that the system formed from initially substructured con...
