Effervescence‐Inspired Self‐Healing Plastrons for Long‐Term Immersion Stability
Advanced Functional Materials, Volume 32, Issue 4, January 19, 2022., 2022 Underwater performance of superhydrophobic/superamphiphobic surfaces relies on the robustness and durability of the gas‐layer (plastron). A simple and scalable technique of effervescence‐inspired on‐demand plastron repair is presented. Surfaces do not suffer from any performance‐losses even after 2 months of continuous immersion.

The Fundamental Connections between the Solar System and Exoplanetary Science
Journal of Geophysical Research: Planets, Volume 126, Issue 2, February 2021., 2021 Abstract Over the past several decades, thousands of planets have been discovered outside our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution.

A Relativistic Compact Stellar Model of Anisotropic Quark Matter Mixed with Dark Energy
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The possibility of strange stars mixed with dark energy to be one of the candidates for dark energy stars is the main issue of the present study. Our investigation shows that quark matter atcs as dark energy after a certain yet unknown critical condition inside the quark stars.

Detecting Multiplanetary Systems with Gravitational Microlensing and the Roman Space Telescope
The Astronomical Journal, 2023 It is plausible that most of the Stars in the Milky Way Galaxy, like the Sun, consist of planetary systems, instead of a single planet. Out of the estimately discovered 3980 planet-hosting stars, about 860 of them are known to be multiplanetary systems ...

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 The perturbation caused by planet‐moon binarity on the time‐of‐arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet‐moon system inclined of an angle α with respect to the plane of the orbit of the planet‐moon barycenter around the pulsar.

Dark Matter Halos from the Inside Out
Advances in Astronomy, Volume 2011, Issue 1, 2011., 2011 The balance of evidence indicates that individual galaxies and groups or clusters of galaxies are embedded in enormous distributions of cold, weakly interacting dark matter. These dark matter “halos” provide the scaffolding for all luminous structures in the universe, and their properties comprise an essential part of the current cosmological model.

Automated Detection of Short Optical Transients of Astrophysical Origin in Real Time
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 The detection of short optical transients of astrophysical origin in real time is an important task for existing robotic telescopes. The faster a new optical transient is detected, the earlier follow‐up observations can be started. The sooner the object is identified, the more data can be collected before the source fades away, particularly in the most

The Astrophysical Journal, 1992 If the dark matter in the Galactic halo consists of compact objects in the 10 −6 -10 2 M ⊙ mass range, it can be detected as it gravitationally microlenses stars in neighboring galaxies and the Galactic bulge. Though extremely rare, microlensing has several powerful signatures: the light curves follow a well-known function, are time symmetric, and ...

Robotic Astronomy with the Faulkes Telescopes and Las Cumbres Observatory Global Telescope
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 We present results from ongoing science projects conducted by members of the Faulkes Telescope (FT) team and Las Cumbres Observatory Global Telescope (LCOGT). Many of these projects incorporate observations carried out and analysed by FT users, comprising amateur astronomers and schools.
