| '''TOI-1452''' is a star system located in the constellation of [[Draco_(constellation)|Draco]]. It is a binary pair of dim red dwarf stars separated by only 96 [[Astronomical unit|astronomical units]] (AU). A notable feature of this system is the presence of an exoplanet around one of the stars, designated as [[TOI-1452 b]].<ref name="OceanWorld">{{Cite web |title=Discovery of Ocean World with the CFHT |url=https://www.cfht.hawaii.edu/en/news/OceanWorld/ |website=Canada-France-Hawaii Telescope |access-date=2023-09-14}}</ref> The secondary star is often distinguished from the first with the name "'''TOI-1760'''".<ref name=":0" /> | |
| ==Properties== | |
| TOI-1452 is 99 light-years away from Earth.<ref name="StellarCatalog"/> It is two M4 dwarf stars that were observed by [[Transiting Exoplanet Survey Satellite|TESS]] as a priority, since they are on the [[cool dwarf list]], a list of high-priority orange-red and red dwarf stars, that was uploaded to TESS. It is a flare star, with a flare observed by TESS where the star brightened by 5%.<ref name=":0">{{Cite journal |last1=Cadieux |first1=Charles |last2=Doyon |first2=René |last3=Plotnykov |first3=Mykhaylo |last4=Hébrard |first4=Guillaume |last5=Jahandar |first5=Farbod |last6=Artigau |first6=Étienne |last7=Valencia |first7=Diana |last8=Cook |first8=Neil J. |last9=Martioli |first9=Eder |last10=Vandal |first10=Thomas |last11=Donati |first11=Jean-François |last12=Cloutier |first12=Ryan |last13=Narita |first13=Norio |last14=Fukui |first14=Akihiko |last15=Hirano |first15=Teruyuki |date=2022-08-12 |title=TOI-1452 b: SPIRou and TESS Reveal a Super-Earth in a Temperate Orbit Transiting an M4 Dwarf |journal=The Astronomical Journal |volume=164 |issue=3 |pages=96 |doi=10.3847/1538-3881/ac7cea |issn=0004-6256 |doi-access=free |arxiv=2208.06333 }}</ref> | |
| ==Exoplanet== | |
| In 2022, an exoplanet was detected orbiting one of the stars every 11 days. The planet, named TOI-1452b, is a [[super-Earth]] and potential [[ocean world]] with a mass 4.8 times that of Earth and a radius 1.67 times that of Earth.<ref name="OceanWorld"/><ref name=":0" /> | |
| ==Observation== | |
| The star system is too dim to be seen with small telescopes, with an [[apparent magnitude]] of +14.4.<ref name="StellarCatalog">{{Cite web |title=TOI-1452 Star Information |url=https://www.stellarcatalog.com/stars/toi-1452 |website=Stellar Catalog |access-date=2023-09-14}}</ref> | |
