The Evidence for a Binary origin of the Young Planetary Nebula HB 12 [PDF]
, 2006 The young planetary nebulae play an important role in stellar evolution when intermediate- to low-mass stars (0.8 $\sim$ 8 M$_\odot$) evolve from the proto-planetary nebulae phase to the planetary nebulae phase.

Binary Central Stars of Planetary Nebulae
Galaxies, 2020 It is now clear that a vast majority of intermediate-mass stars have stellar and/or sub-stellar companions, therefore it is no longer appropriate to consider planetary nebulae as a single-star phenomenon, although some single, isolated stars may well ...

Progress in Earth and Planetary Science, 2021 In the East Asian monsoon area, stalagmites generally record lower and higher oxygen isotope (δ18O) levels during warm humid interglacial and cold dry glacial periods, respectively.

The maximum mass of planetary embryos formed in core-accretion models [PDF]
, 2017 We compute the maximum mass a growing planetary embryo can reach depending on the size of accreted planetesimals or pebbles, to infer the possibility of growing the cores of giant planets, and giant planets themselves.

Cloud Atlas: Rotational Spectral Modulations and Potential Sulfide Clouds in the Planetary-mass, Late T-type Companion Ross 458C [PDF]
Astrophysical Journal, 2019 Measurements of photometric variability at different wavelengths provide insights into the vertical cloud structure of brown dwarfs and planetary-mass objects.

The Astrophysical Journal, 2023 Fundamental to our understanding of planetary bulk compositions is the relationship between their masses and radii, two properties that are often not simultaneously known for most exoplanets.

Impact of Planetary Mass Uncertainties on Exoplanet Atmospheric Retrievals [PDF]
Astrophysical Journal, 2019 In current models used to interpret exoplanet atmospheric observations, the planetary mass is treated as a prior and is measured/estimated independently with external methods, such as radial velocity or transit timing variation techniques.

Ohmic Dissipation During the Formation of Super-Earth
The Astrophysical Journal, 2023 The super-Earth population, as one of the representatives of exoplanets, plays an important role in constraining the planet formation theories. According to the prediction from core-accretion models, super-Earths should be rare because their masses are ...

System initial mass function of the 25 Ori group from planetary-mass objects to intermediate/high-mass stars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The stellar initial mass function (IMF) is an essential input for many astrophysical studies but only in a few cases has it been determined over the whole cluster mass range, limiting the conclusions about its nature.

The Cosmic Zoo: The (Near) Inevitability of the Evolution of Complex, Macroscopic Life
Life, 2016 Life on Earth provides a unique biological record from single-cell microbes to technologically intelligent life forms. Our evolution is marked by several major steps or innovations along a path of increasing complexity from microbes to space-faring ...
