On the Detection of Exomoons Transiting Isolated Planetary-mass Objects [PDF]
Astrophysical Journal Letters, 2021 All-sky imaging surveys have identified several dozen isolated planetary-mass objects (IPMOs) far away from any star. Here we examine the prospects for detecting transiting moons around these objects.

Dynamic changes in optical and chemical properties of tar ball aerosols by atmospheric photochemical aging [PDF]
Atmospheric Chemistry and Physics, 2019 Following wood pyrolysis, tar ball aerosols were laboratory generated from wood tar separated into polar and nonpolar phases. Chemical information of fresh tar balls was obtained from a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS)

On the Dependence of Planetary Spin on Mass [PDF]
American Journal of Astronomy and Astrophysics, 2014 The recent direct spectroscopic observation of the spin of the young gas giant exoplanet ? Pictoris b was a powerful clue as to the general validity of the trend of the planetary spin with the mass even outside the Solar System. Nevertheless, the spin-mass relationship, which looks like to hold irrespective of the planet composition and radius, is ...

Evidence for benthic–pelagic food web coupling and carbon export from California margin bamboo coral archives [PDF]
Biogeosciences, 2014 Deep-sea bamboo corals (order Gorgonacea, family Isididae) are known to record changes in water mass chemistry over decades to centuries. These corals are composed of a two-part skeleton of calcite internodes segmented by gorgonin organic nodes.

Size-Resolved Community Structure of Bacteria and Fungi Transported by Dust in the Middle East
Frontiers in Microbiology, 2021 The atmosphere plays an important role in transporting microorganisms on a global scale, yet the processes affecting the composition of the airborne microbiome, the aerobiome, are not fully outlined. Here we present the community compositions of bacteria

As the Worlds Turn: Constraining Spin Evolution in the Planetary-mass Regime [PDF]
Astrophysical Journal, 2020 To understand how planetary spin evolves and traces planet formation processes, we measure rotational line broadening in eight planetary-mass objects (PMOs) of various ages (1–800 Myr) using near-infrared high-resolution spectra from NIRSPEC/Keck ...

On the Potential of Silicon as a Building Block for Life
Life, 2020 Despite more than one hundred years of work on organosilicon chemistry, the basis for the plausibility of silicon-based life has never been systematically addressed nor objectively reviewed.

Strong Hα emission and signs of accretion in a circumbinary planetary mass companion from MUSE [PDF]
Astronomy & Astrophysics, 2020 Context. Intrinsic Hα emission can be advantageously used to detect substellar companions because it improves contrasts in direct imaging. Characterising this emission from accreting exoplanets allows for the testing of planet formation theories.
