Space Weather, 2022 The present study aims at characterizing the habitability conditions of exoplanets with an Earth‐like magnetosphere inside the habitable zone of M and F stars, caused by the direct deposition of the stellar wind on the exoplanet surface.

CD-HPF: New Habitability Score Via Data Analytic Modeling
, 2016 The search for life on the planets outside the Solar System can be broadly classified into the following: looking for Earth-like conditions or the planets similar to the Earth (Earth similarity), and looking for the possibility of life in a form known or

, 2021 The internal structure of any planet is the result of its composition, radiation environment and age. Exoplanet interiors are hidden worlds that we are offered a glimpse into via the measurements of the most fundamental planet parameters; radius and mass. With this knowledge, we can distinguish rocky Earth-like planets from gaseous giants.

Neuromorphic Computing with Memcapacitors: Advancements, Challenges, and Future Directions
Advanced Electronic Materials, EarlyView.Neuromorphic computing reduces energy costs by integrating memory and processing in event‐driven architectures, achieving energy usage as low as 10–30 pJ per operation for memcapacitor‐based synapses. Memcapacitors are reviewed as strong contenders for neuromorphic computing, enhancing AI acceleration through charge‐based computations, high resistance,

Frontiers in Astronomy and Space Sciences, 2022 We present a new synergic strategy that merges the potential of asteroseismology with solar space weather/climate techniques in order to characterize solar-like stars and their interaction with hosted exoplanets. The method is based on the use of seismic

, 2016 For the last few decades the study of disks around stars young and old and of different types have progressed significantly. During the same time a completely new discipline, the study of exoplanets, planets orbiting stars other than our Sun, have ...

Challenges, 2014 Rational speculation about biological evolution on other worlds is one of the outstanding challenges in astrobiology. With the growing confirmation that multiplanetary systems abound in the universe, the prospect that life occurs redundantly throughout ...

Is there an exoplanet in the Solar system? [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2016 Abstract We investigate the prospects for the capture of the proposed Planet 9 from other stars in the Sun's birth cluster. Any capture scenario must satisfy three conditions: the encounter must be more distant than ∼150 au to avoid perturbing the Kuiper belt; the other star must have a wide-orbit planet (a ≳ 100 au); the planet must be ...

Distinguishing multicellular life on exoplanets by testing Earth as an exoplanet [PDF]
International Journal of Astrobiology, 2020 AbstractCan multicellular life be distinguished from single cellular life on an exoplanet? We hypothesize that abundant upright photosynthetic multicellular life (trees) will cast shadows at high sun angles that will distinguish them from single cellular life and test this using Earth as an exoplanet.

Shaping of Planetary Nebulae by Exoplanets
Galaxies, 2020 (1) Background: We investigate the hypothesis that exoplanet engulfment can help explain the observed non-spherical planetary nebula population, as a complementary shaping mechanism to the binary hypothesis.
