Solar analogs as a research area focuses on the identification, characterization, and comparative study of stars with physical properties closely matching those of the Sun, typically in terms of effective temperature, luminosity, mass, metallicity, age, and spectral type (usually G-type dwarfs). This field investigates how solar-like conditions influence stellar structure and evolution, dynamo-driven magnetic activity, rotation, and coronal and chromospheric behavior. It also underpins comparative planetary system studies and habitability assessments by providing statistically meaningful analog populations that constrain solar history, solar variability, and the broader context of Sun-like stars within galactic stellar populations.
"Are we alone?" This ancient question has occupied humanity's mind for a long time. In 1995, the discovery of the first exoplanet orbiting a sun-like star opened the door to exploring this profound mystery.

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a research paper published May ...
We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit harder to spot.

There is no question that the sun is a temperamental star, as this year's unusually strong solar storms show. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious?

The first dark comet—a celestial object that looks like an asteroid but moves through space like a comet—was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce the discovery ...

Buried in the treasure trove of the Gaia catalog were two strange black hole systems. These were black holes orbiting sun-like stars, a situation that astronomers long thought impossible. Recently, a team has proposed a mechanism ...
