A constant upper luminosity limit of cool supergiant stars down to the extremely low metallicity of I Zw 18
Stellar wind mass loss is often assumed to depend on their metallicity $Z$. Therefore, evolutionary models of massive stars at lower $Z$ are able to retain more of their H-rich layers and evolve into brighter cool supergiants (cool SGs; $T_\mathrm{eff} < 7$ kK). Surprisingly, in galaxies in the range $0.2 \lesssim Z / Z_\odot \lesssim 1.5$ previous studies did not find a $Z$-dependence of the upper luminosity limit $L_\mathrm{max}$ of cool SGs. Here, we study four extra galaxies with HST and JW…

Australia to create a national park for 12,000 koalas
Few animals tug at Australian hearts like the koala. Yet the marsupial, once common along the eastern seaboard, was declared endangered in New South Wales (NSW) in 2022. Habitat loss, climate stress, and disease have driven populations down so far that a parliamentary inquiry warned they could vanish from the state before 2050. The proposed […]

Revisiting FRB 20121102A: milliarcsecond localisation and a decreasing dispersion measure
FRB 20121102A is the original repeating fast radio burst (FRB) source and also the first to be localised to milliarcsecond precision using very-long-baseline interferometry (VLBI). It has been active for over 13 years and resides in an extreme magneto-ionic environment in a dwarf host galaxy at a distance of ~1 Gpc. In this work, we use the European VLBI Network (EVN) to (re-)localise FRB 20121102A and its associated persistent radio source (PRS). We confirm that the two are co-located -- impro…

TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc
We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling comparisons with the $β$ Pictoris and Solar System size distributions. Twenty-four transits with absorption depths (AD) of 1--20\% were observed across three TESS sectors of the 20-50 Myr K0V star, detected as part of our TESS survey of extreme debris disks identified by their IR excess. We discover that the ADs (and …
