TESS Hunt for Young and Maturing Exoplanets

TESS Hunt for Young and Maturing Exoplanets (THYME) is an exoplanet search project. The researchers of the THYME collaboration are mainly from the United States{{Cite journal |last1=Newton |first1=Elisabeth R. |last2=Mann |first2=Andrew W. |last3=Tofflemire |first3=Benjamin M. |last4=Pearce |first4=Logan |last5=Rizzuto |first5=Aaron C. |last6=Vanderburg |first6=Andrew |last7=Martinez |first7=Raquel A. |last8=Wang |first8=Jason J. |last9=Ruffio |first9=Jean-Baptiste |last10=Kraus |first10=Adam L. |last11=Johnson |first11=Marshall C. |last12=Thao |first12=Pa Chia |last13=Wood |first13=Mackenna L. |last14=Rampalli |first14=Rayna |last15=Nielsen |first15=Eric L. |date=2019-07-01 |title=TESS Hunt for Young and Maturing Exoplanets (THYME): A Planet in the 45 Myr Tucana-Horologium Association |journal=The Astrophysical Journal |volume=880 |issue=1 |pages=L17 |doi=10.3847/2041-8213/ab2988 |arxiv=1906.10703 |bibcode=2019ApJ...880L..17N |issn=0004-637X|hdl=1721.1/124722 |hdl-access=free |doi-access=free }}{{Cite journal |last1=Newton |first1=Elisabeth R. |last2=Rampalli |first2=Rayna |last3=Kraus |first3=Adam L. |last4=Mann |first4=Andrew W. |last5=Curtis |first5=Jason L. |last6=Vanderburg |first6=Andrew |last7=Krolikowski |first7=Daniel M. |last8=Huber |first8=Daniel |last9=Petter |first9=Grayson C. |last10=Bieryla |first10=Allyson |last11=Tofflemire |first11=Benjamin M. |last12=Thao |first12=Pa Chia |last13=Wood |first13=Mackenna L. |last14=Kerr |first14=Ronan |last15=Safanov |first15=Boris S. |date=2022-09-01 |title=TESS Hunt for Young and Maturing Exoplanets (THYME).

Paper number 8 adapted the backronym to "Transit Hunt for Young and Maturing Exoplanets", because it used data from the Kepler space telescope.{{Cite journal |last1=Barber |first1=Madyson G. |last2=Mann |first2=Andrew W. |last3=Bush |first3=Jonathan L. |last4=Tofflemire |first4=Benjamin M. |last5=Kraus |first5=Adam L. |last6=Krolikowski |first6=Daniel M. |last7=Vanderburg |first7=Andrew |last8=Fields |first8=Matthew J. |last9=Newton |first9=Elisabeth R. |last10=Owens |first10=Dylan A. |last11=Thao |first11=Pa Chia |date=2022-09-01 |title=Transit Hunt for Young and Maturing Exoplanets (THYME).
