Stellar binaries are very common. This statement certainly applies to the Milky Way galaxy, including the solar system neighborhood. The purpose of this special issue, entitled "Habitability of Planets in Stellar Binary Systems", is to provide an update overview of the prospect of the habitability in binary systems considering the large body of results, encompassing both observations and theoretical work. Regarding the former, planets have been identified in different types of binary systems, as they can be part of different kinds of star–planet configurations. Previous theoretical studies focused on the likelihood of habitability need to be reconsidered, as for some systems the geometrical extent of the habitable zone may have been truncated due to the planetary orbital stability requirement. Some of these results are also expected to depend on the adopted planetary climate model, and may furthermore be shaped by different kinds of star–planet interactions. Akin to single stars, the possibility of planetary habitability may also be impacted by the mode and strength of stellar activity, including but not limited to energetic radiation and winds. Most fundamentally, the formation of planets in binary systems and the impact of stellar evolution on the habitability of planets also deserve careful consideration.Prof. Dr. Cesare Chiosi

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Galaxies is an international peer-reviewed open access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
