Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies
Astronomische Nachrichten, Volume 347, Issue 2, February 2026.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.

Signs of Similar Stellar Obliquity Distributions for Hot and Warm Jupiters Orbiting Cool Stars
The Astronomical JournalTransiting giant planets provide a natural opportunity to examine stellar obliquities, which offer clues about the origin and dynamical histories of close-in planets.

A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
, 2010 We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an average stellar specific dissipation function Q_* in the ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

Most Super-Earths Have Less Than 3% Water
The Astrophysical JournalSuper-Earths are highly irradiated, small planets with bulk densities approximately consistent with Earth. We construct combined interior atmosphere models of super-Earths that trace the partitioning of water throughout a planet, including an iron-rich ...

, 2008 The timescale over which planets may form in the circumstellar disks of young stars is one of the main issues of current planetary formation models. We present here new constraints on planet formation timescales derived from the rotational evolution of ...

Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets
The Astrophysical JournalAs the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

The Polar Orbit of TOI-2374 b, a Planet in the Neptunian Ridge
The Astronomical JournalThe “Neptunian ridge” is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and 6 days.
