Formation of the resonant system HD 60532 [PDF]
, 2010 Among multi-planet planetary systems there are a large fraction of resonant systems. Studying the dynamics and formation of these systems can provide valuable informations on processes taking place in protoplanetary disks where the planets are thought ...

Advanced Engineering Materials, EarlyView.Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Formation of Ultra-short-period Planets in Hot Jupiter Systems: Application to WASP-47
The Astrophysical Journal LettersThe WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as the innermost planetary companion.

The architecture and formation of the Kepler-30 planetary system
, 2018 We study the orbital architecture, physical characteristics of planets, formation and long-term evolution of the Kepler-30 planetary system, detected and announced in 2012 by the KEPLER team.

Formation and Evolution of Planetary Systems in Presence of Highly Inclined Stellar Perturbers [PDF]
, 2011 The presence of highly eccentric extrasolar planets in binary stellar systems suggests that the Kozai effect has played an important role in shaping their dynamical architectures.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Dust Drift Timescales in Protoplanetary Disks at the Cusp of Gravitational Instability
The Astrophysical JournalMillimeter emitting dust grains have sizes that make them susceptible to drift in protoplanetary disks due to the difference between their orbital speed and that of the gas. The characteristic drift timescale depends on the surface density of the gas. By

Enhanced Size Uniformity for Near-resonant Planets
The Astrophysical Journal, 2023 Super-Earths within the same close-in, compact planetary system tend to exhibit a striking degree of uniformity in their radius, mass, and orbital spacing, and this “peas-in-a-pod” phenomenon itself serves to provide one of the strongest constrains on ...

Planetary Systems Around Red Giants and Formation of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 2003 The effects of planetary systems around pre-AGB and AGB stars on their pulsations, optical spectra and on the shape of future planetary nebulae are discussed. The physical phenomena considered include include gas drag on the planet embedded in the ever denser circumstellar gas of a red giant and shock waves arising.

On the formation age of the first planetary system [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractRecently, it has been observed the extreme metal-poor stars in the Galactic halo, which must be formed just after Pop III objects. On the other hand, the first gas clouds of mass ∼ 106 M⊙ are supposed to be formed at z ∼ 10, 20, and 30 for the 1σ, 2σ and 3σ, where the density perturbations are assumed of the standard ΛCDM cosmology.
