A Rotation Rate for the Planetary-mass Companion DH Tau b [PDF]
Astronomical Journal, 2020 DH Tau b is a young planetary-mass companion orbiting at a projected separation of 320 au from its ∼2 Myr old host star DH Tau. With an estimated mass of 8–22 this object straddles the deuterium-burning limit, and might have formed via core or pebble ...

Isotopic evolution of planetary crusts by hypervelocity impacts evidenced by Fe in microtektites
Nature Communications, 2021 Fe isotopic composition of the distal ejecta of a terrestrial impact crater records both evaporation and condensation, refining the nature of the isotopic fractionation taking place during hypervelocity impacts in the Solar System.

A Wide Planetary-mass Companion to a Young Low-mass Brown Dwarf in Ophiuchus [PDF]
Astrophysical Journal, 2020 We present the discovery of a planetary-mass companion to CFHTWIR-Oph 98, a low-mass brown dwarf member of the young Ophiuchus star-forming region, with a wide 200 au separation (1.″46).

Masses of the Central Stars of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1997 The aim of this study is to derive the masses of the central stars (CSPN) for a large sample of the planetary nebulae (PN). These masses, M∗, are derived from the observed PN positions in three diagnostic diagrams and their comparison with evolutionary tracks of model PN.

Limits on Planetary-mass Primordial Black Holes from the OGLE High-cadence Survey of the Magellanic Clouds [PDF]
Astrophysical Journal LettersObservations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or wide-orbit exoplanets.

The New Generation Planetary Population Synthesis (NGPPS). IV. Planetary systems around low-mass stars [PDF]
Astronomy & Astrophysics, 2021 Previous work concerning planet formation around low-mass stars has often been limited to large planets and individual systems. As current surveys routinely detect planets down to terrestrial size in these systems, a more holistic approach that reflects ...

Natural Products Containing ‘Rare’ Organophosphorus Functional Groups
Molecules, 2019 Phosphorous-containing molecules are essential constituents of all living cells. While the phosphate functional group is very common in small molecule natural products, nucleic acids, and as chemical modification in protein and peptides, phosphorous can ...
