Planet-driven Spiral Arms in Protoplanetary Disks. I. Formation Mechanism [PDF]

Astrophysical Journal, 2017
Protoplanetary disk simulations show that a single planet can excite more than one spiral arm, possibly explaining the recent observations of multiple spiral arms in some systems. In this paper, we explain the mechanism by which a planet excites multiple

Uncovering Spiral Structure in Flocculent Galaxies [PDF]

, 1996
We present K'(2.1 micron) observations of four nearby flocculent spirals, which clearly show low-level spiral structure and suggest that kiloparsec-scale spiral structure is more prevalent in flocculent spirals than previously supposed.

Dynamically Driven Evolution of the Interstellar Medium in M51 [PDF]

, 2009
Massive star formation occurs in giant molecular clouds (GMCs); an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the highest-fidelity observations of the grand-design spiral

Strain Effects in Twisted Spiral Antimonene

Advanced Science, 2023
Van der Waals (vdW) layered materials exhibit fruitful novel physical properties. The energy band of such materials depends strongly on their structures, and a tremendous variation in their physical properties can be deduced from a tiny change in inter ...

SPIRAL: Extreme Performance Portability

Proceedings of the IEEE, 2018
In this paper, we address the question of how to automatically map computational kernels to highly efficient code for a wide range of computing platforms and establish the correctness of the synthesized code.

Futurizing ‘good construction(s)’: ‘Low-carbon’ and ‘labor’ futures in the Belgian construction sector

TATuP – Zeitschrift für Technikfolgenabschätzung in Theorie und Praxis
In this article, we explore through a foresight exercise how the construction sector in Belgium envisions its transition until 2050. Drawing on the notion of “the good economy” (Asdal et al.

Angular Momentum across the Hubble sequence from the CALIFA survey [PDF]

, 2014
We investigate the stellar angular momentum of galaxies across the Hubble sequence from the CALIFA survey. The distribution of CALIFA elliptical and lenticular galaxies in the $\lambda_{\rm Re}-\epsilon_{\rm e}$ diagram is consistent with that shown by ...

The Morphological Aberrations of Cystic Duct and its Clinical Significance: A Gross Anatomical Study

International Journal of Anatomy Radiology and Surgery, 2018
Introduction: The Cystic Duct (CD) serves as a thorough fare for transport of bile to and away from the gallbladder. It is about 2-4 cm in length and 1-5 mm in diameter, and joins the Common Hepatic Duct (CHD) at its right lateral aspect, in the ...
