Does iron chelation by eumelanin contribute to the ethnic link with maternal mortality? (2022)
Journal Article
(2022). Does iron chelation by eumelanin contribute to the ethnic link with maternal mortality?. European Journal of Obstetrics and Gynecology and Reproductive Biology, 107 - 108. https://doi.org/10.1016/j.ejogrb.2022.09.012

Significant disparities in maternal mortality between white and black mothers have been noted for over 80 years and remain an extremely serious problem. Black women are still four times more likely than white women to die in pregnancy or childbirth i...

Magnetic fields can drastically change predictions of evolutionary models of massive stars via mass-loss quenching, magnetic braking, and efficient angular momentum transport, which we aim to quantify in this work. We use the MESA software instrument... Read More about The effects of surface fossil magnetic fields on massive star evolution: IV. Grids of models at Solar, LMC, and SMC metallicities.

Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwarf component for which direct measurements of these stars' masses and r... Read More about The EBLM project – IX.

Infrared spectroscopy of the 2019 eruption of the recurrent nova V3890 Sgr: Separation into equatorial and polar winds revealed (2022)
Journal Article

We present infrared spectroscopy of the 2019 eruption of the recurrent nova V3890 Sgr, obtained over the period 5.1–46.3 days after the eruption. The spectrum of the red giant became more prominent as the flux declined, and by day 46.3 dominated the...

Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.e., elements heavier than helium, also called "metallicity"), and thus...
