Performance The Red Onion (Allium ascalonicum L.) by Husk Charcoal and Fertilizer K Application
Journal of Tropical Soils, 2023 The cultivation of Red Onions (Allium ascalonicum, L.) in paddy fields needs to be investigated further because paddy fields have constraints on the soil physical and chemical properties, such as soil structure, drainage, pH, and nutrient availability ...

Star clusters with dual red clumps [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractA few star clusters in the Magellanic Clouds exhibit composite structures in the red-clump region of their colour–magnitude diagrams. The most striking case is NGC 419 in the Small Magellanic Cloud (SMC), where the red clump is composed of a main blob as well as a distinct secondary feature.

Evidence of structural discontinuities in the inner core of red-giant stars
Nature Communications, 2022 Red giant stars enter the clump phase as the helium in the cores start fusing. Here, the authors show evidence for large core structural discontinuities in 7% of Kepler satellite clump star data implying that the mixing region beyond the convective core ...

The Mid-infrared Molecular Inventory toward Orion IRc2
The Astrophysical Journal, 2023 We present the first high spectral resolution mid-infrared survey in the Orion BN/KL region, covering 7.2–28.3 μ m. With SOFIA/EXES, we target the enigmatic source Orion IRc2.

Modelling the Galactic Bar using Red Clump Stars [PDF]
International Astronomical Union Colloquium, 1996 AbstractThe color-magnitude diagrams of ~ 1 × 106 stars obtained for 19 fields towards the Galactic bulge with the OGLE project reveal a well-defined population of bulge red clump stars. We found that the distributions of the extinction-adjusted apparent magnitudes of red clump stars in fields lying at ι = ±5° in galactic longitude differ by ∼ 0.4 mag.

Investigating APOKASC Red Giant Stars with Abnormal Carbon-to-nitrogen Ratios
The Astrophysical Journal, 2023 The success of galactic archeology and the reconstruction of the formation history of our Galaxy relies critically on precise ages for large populations of stars. For evolved stars in the red clump and red giant branch, the carbon-to-nitrogen ratio ([C/N]

Inferring Coupling Strengths of Mixed-mode Oscillations in Red Giant Stars Using Deep Learning
The Astrophysical Journal, 2023 Asteroseismology is a powerful tool that may be applied to shed light on stellar interiors and stellar evolution. Mixed modes, behaving like acoustic waves in the envelope and buoyancy modes in the core, are remarkable because they allow for probing the ...
