The multiplicity of exoplanet host stars - New low-mass stellar companions of the exoplanet host stars HD125612 and HD212301

open access: yes, 2008
Aims: We present new results from our ongoing multiplicity study of exoplanet host stars, carried out with SofI/NTT. We provide the most recent list of confirmed binary and triple star systems that harbor exoplanets.

Binary-lens Microlensing Degeneracy: Impact on Planetary Sensitivity and Mass-ratio Function

open access: yesThe Astronomical Journal
Gravitational microlensing is a unique method for discovering cold planets across a broad mass range. Reliable statistics of the microlensing planets require accurate sensitivity estimates.

Spectrometric method for detecting exoplanets as another test to verify the invariance of the velocity of light [PDF]

open access: yesMoscow University Physics Bulletin, 2011
Hypothetical influences of variability of light velocity due to the parameters of the source of radiation, for the results of spectral measurements of stars to search for exoplanets are considered. Accounting accelerations of stars relative to the barycenter of the star - a planet (the planets) was carried out.

Altitude Profile and Isotopic Composition for N2 From Pioneer Venus Mass Spectra

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract We report the highest resolution altitude profile and isotopic composition for N2 at Venus, to date. These results were obtained through re‐analysis of data acquired by the Pioneer Venus Large Probe Neutral Mass Spectrometer (LNMS). The N2 is non‐uniformly mixed across the clouds and sub‐cloud atmosphere (∼59–15 km) yet uniformly mixed across ...

Kepler Observations of Three Pre-Launch Exoplanet Candidates: Discovery of Two Eclipsing Binaries and a New Exoplanet

open access: yes, 2010
Three transiting exoplanet candidate stars were discovered in a ground-based photometric survey prior to the launch of NASA's {\it Kepler} mission. {\it Kepler} observations of them were obtained during Quarter 1 of the {\it Kepler} mission.

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

The Giant Accreting Protoplanet Survey (GAPlanetS)—Results from a 6 yr Campaign to Image Accreting Protoplanets

open access: yesThe Astronomical Journal, 2023
Accreting protoplanets are windows into planet formation processes, and high-contrast differential imaging is an effective way to identify them. We report results from the Giant Accreting Protoplanet Survey (GAPlanetS), which collected H α differential ...
