The T16 Planet Hunt: 10,000 New Planet Candidates from TESS Cycle 1 and the Confirmation of a Hot Jupiter Around TIC 183374187

Joshua T. Roth, Joel D. Hartman, Gáspár Á. Bakos +12

The T16 project has produced a uniformly detrended and systematics-corrected set of 83,717,159 TESS Cycle 1 full-frame image light curves for stars observed by TESS in its primary…

Detailed spectroscopic and photometric analysis of the remarkable planet-hosting wide binary system HD 202772A/B

Emiliano Jofré, Yilen Gómez Maqueo Chew, Romina Petrucci +15

We conducted a detailed spectroscopic and photometric characterization of the planet-hosting wide binary HD 202772A/B. No planet has been detected around HD 202772B, whereas HD 202…

Disentangling the origin of chemical differences using GHOST

C. Saffe, P. Miquelarena, J. Alacoria +8

Aims. We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD 138202 + CD-30 12303. For the first time, we suggest ho…

Elemental abundances differences in the massive planet-hosting wide binary HD 196067-68

M. Flores, J. Yana Galarza, P. Miquelarena +6

It has been suggested that small chemical anomalies observed in planet-hosting wide binary systems could be due to planet signatures, where the role of the planetary mass is still…

Detecting prolonged activity minima in binary stars. The case of Ret

M. Flores, M. Jaque Arancibia, R. V. Ibañez Bustos +7

Context. It is well known that from 1645 to 1715 solar activity was notably low and the number of sunspots was extremely reduced. This epoch is known as the Maunder Minimum (MM). T…
