PERICLES: A Set of Empirical Rotational Isochrones Modeled on Cool Dwarfs in Open Clusters and Wide Binaries

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.

A Proposed Circular Economy Readiness Framework for the Rail Sector, A Literature Review and Conceptual Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) offers a transformative approach to addressing global sustainability challenges, yet few frameworks integrate it with business strategy, systems thinking (ST) and asset management (AM), especially within critical infrastructure sectors like rail. This paper conducts a comprehensive literature review to assess existing

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

open access: yesChemCatChem, EarlyView.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.
