Context. The NASA mission TESS is currently doing an all-sky survey from space to detect transiting planets around bright stars. As part of the validation process, the most promising planet candidates need to be confirmed and characterized using follow-up observations. Aims. In this article, our aim is to confirm the planetary nature of the transiting planet candidate TOI-674b using spectroscopic and photometric observations. Methods. We use TESS, Spitzer, ground-based light curves, and HARPS spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate TOI-674b. We perform a joint fit of the light …

We announce the discovery of KELT-16b, a highly irradiated, ultra-short period hot Jupiter transiting the relatively bright (V = 11.7) star TYC 2688-1839-1/KELT-16. A global analysis of the system shows KELT-16 to be an F7V star with ${T}_{\mathrm{eff}}=6236\pm 54$ K, $\mathrm{log}{g}_{\star }={4.253}_{-0.036}^{+0.031}$, $[\mathrm{Fe}/{\rm{H}}]=-{0.002}_{-0.085}^{+0.086}$, ${M}_{\star }={1.211}_{-0.046}^{+0.043}\,{M}_{\odot }$, and ${R}_{\star }\,={1.360}_{-0.053}^{+0.064}{R}_{\odot }$. The planet is a relatively high-mass inflated gas giant with ${M}_{{\rm{P}}}={2.75}_{-0.15}^{+0.16}{M}_{{\rm{J}}}$, ${R}_{{\rm{P}}}={1.415}_{-0.067}^{+0.084}{R}_{{\rm{J}}}$, density ${\rho }_{{\rm{P}}}=1.20\pm 0.18$ g cm−3, surface gravity $\mathrm{log}\,{g}_{{\rm{P}}}={3.530}_{-0.049}^{+0.042}$, and ${T}_{\mathrm{eq}}={2453}_{-47}^{+55}$ K. The best-fitting linear ephemeris is ${T}_{{\rm{C}}}=2457247.24791\pm 0.00019$ ${\mathrm{BJD}}_{\mathrm{TDB}}\ $and $P=0.9689951\pm 0.0000024$ day. KELT-16b joins WASP-18b, −19b, −43b, −103b, and HATS-18b as the only giant transiting planets …

We report the discovery of KELT-4Ab, an inflated, transiting Hot Jupiter orbiting the brightest component of a hierarchical triple stellar system. The host star is an F star with ${T}_{{\rm{eff}}}$ = $6206\pm 75$ K, $\mathrm{log}g$ = $4.108\pm 0.014$, $[{\rm{Fe}}/{\rm{H}}]$ = $-{0.116}_{-0.069}^{+0.065}$, ${M}_{*}$ = ${1.201}_{-0.061}^{+0.067}$ $\;{M}_{\odot }$, and ${R}_{*}$ = ${1.603}_{-0.038}^{+0.039}$ $\;{R}_{\odot }$. The best-fit linear ephemeris is ${\mathrm{BJD}}_{\mathrm{TDB}}$ $\;=\;2456193.29157\pm 0.00021$ $\quad +\quad E(2.9895936\pm 0.0000048)$. With a magnitude of V ~ 10, a planetary radius of ${1.699}_{-0.045}^{+0.046}$ $\;{R}_{{\rm{J}}}$, and a mass of ${0.902}_{-0.059}^{+0.060}$ $\;{M}_{{\rm{J}}}$, it is the brightest host among the population of inflated Hot Jupiters (RP > 1.5RJ), making it a …
