The Pan-STARRS1 Planet Survey: Overview and first results
EPJ Web of Conferences, 2013 The Pan-STARRS1 Planet Survey (Pan-Planets) is a search for transiting extra-solar planets in the Galactic disk with a focus on planets around M-dwarfs and White dwarfs.

Research Paper: The Effect of the Generalized Uncertainty Principle with Maximum Length on the Size of White Dwarfs [PDF]
فیزیک کاربردی ایرانThe challenge in developing a theory of quantum gravity stems from the fundamentally different ways the two theories describe physical systems. Quantum mechanics operates on discrete, probabilistic principles, while general relativity is a continuous ...

White-Dwarf Asteroseismology With the Kepler Space Telescope
Frontiers in Astronomy and Space Sciences, 2020 In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

Imprint of the Crystallization of Binary White Dwarfs on Gravitational Wave Observations with LISA
Physical Sciences Forum, 2023 Space-based gravitational-wave detectors, such as the Laser Interferometer Space Antenna, allow for the probing of the interior of white dwarfs in binaries through the imprints of tidal effects on the gravitational wave signal.

The effect of $^{22}$Ne diffusion in the evolution and pulsational properties of white dwarfs with solar metallicity progenitors [PDF]
, 2016 Because of the large neutron excess of $^{22}$Ne, this isotope rapidly sediments in the interior of the white dwarfs. This process releases an additional amount of energy, thus delaying the cooling times of the white dwarf.

Advanced Optical Materials, EarlyView.Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Neural Network identification of halo white dwarfs [PDF]
, 1998 The white dwarf luminosity function has proven to be an excellent tool to study some properties of the galactic disk such as its age and the past history of the local star formation rate.

Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities
Advanced Photonics Research, EarlyView.Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.
