A Test of Spectroscopic Age Estimates of White Dwarfs Using Wide WD+WD Binaries
The Astrophysical JournalWhite dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic observations are available. We conduct follow-up spectroscopy of 148 individual

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India
Nordic Journal of Botany, EarlyView.A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

An All-sky Survey of White Dwarf Merger Remnants: Far-Ultraviolet Is the Key
The Astrophysical JournalThe majority of merging white dwarfs leave behind a white dwarf remnant. Hot/warm DQ white dwarfs with carbon-rich atmospheres have high masses and unusual kinematics. All evidence points to a merger origin.

Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas
Nordic Journal of Botany, EarlyView.We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to

The Astrophysical JournalPlanets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...
