THE OVERVIEW OF THE PLANETARY ATMOSPHERIC SPECTRAL TELESCOPE (PAST) IN THE SCIENTIFIC EXPERIMENTAL SYSTEM IN NEAR-SPACE (SENSE) [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
To investigate mass transport and energy dissipation in space environments for solar system planet, a balloon-borne planetary atmospheric spectral telescope (PAST) is designed with 0.8-m aperture in spectral range from 280 nm to 680 nm will

Towards consistent mapping of distant worlds: secondary-eclipse scanning of the exoplanet HD 189733b [PDF]

, 2012
Context. Mapping distant worlds is the next frontier for exoplanet infrared (IR) photometry studies. Ultimately, constraining spatial and temporal properties of an exoplanet atmosphere (e.g., its temperature) will provide further insight into its physics.

Original form of Kepler's Third Law and its misapplication in Propositions XXXII-XXXVII in Newton's Principia (Book I)

Heliyon, 2019
The original form of Kepler's Third Law contains a caveat regarding the requirement of small eccentricities – a fact that has not been incorporated by the traditional Newtonian derivations.

Igneous processes in the small bodies of the Solar System I. Asteroids and comets

iScience, 2023
Summary: Igneous processes were quite widespread in the small bodies of the Solar System (SBSS) and were initially fueled by short-lived radioisotopes, the proto-Sun, impact heating, and differentiation heating.

Accretion of Low Angular Momentum Material onto Black Holes: Two-dimensional Magnetohydrodynamic Case [PDF]

, 2003
We report on the second phase of our study of slightly rotating accretion flows onto black holes. We consider magnetohydrodynamical (MHD) accretion flows with a spherically symmetric density distribution at the outer boundary but with spherical symmetry ...

Galactic planetary science [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
Planetary science beyond the boundaries of our Solar System is today in its infancy. Until a couple of decades ago, the detailed investigation of the planetary properties was restricted to objects orbiting inside the Kuiper Belt. Today, we cannot ignore that the number of known planets has increased by two orders of magnitude nor that these planets ...

Multiple dynamo modes as a mechanism for long-term solar activity variations [PDF]

, 2015
Context. Solar magnetic activity shows both smooth secular changes, such as the modern Grand Maximum, and quite abrupt drops that are denoted as grand minima, such as the Maunder Minimum.

Asymmetric transition disks: Vorticity or eccentricity? [PDF]

, 2013
Context. Transition disks typically appear in resolved millimeter observations as giant dust rings surrounding their young host stars. More accurate observations with ALMA have shown several of these rings to be in fact asymmetric: they have lopsided ...

Accretion of Low Angular Momentum Material onto Black Holes: Two-dimensional Hydrodynamical Inviscid Case [PDF]

, 2002
We report on the first phase of our study of slightly rotating accretion flows onto black holes. We consider inviscid accretion flows with a spherically symmetric density distribution at the outer boundary, but with spherical symmetry broken by the ...
