We present the statistical validation and full photometric characterization of the exoplanet candidate TOI 7475.01 (TIC 376866659), detected by the TESS mission. Using a custom pipeline combining natural flux preservation with robust BLS detection, we identified a transit signal with a period of $3.2538$ days and a depth of $\sim 4600$ ppm. To rule out false positives, we performed centroid analysis, spatial contamination checks using Gaia DR3, and a statistical validation using TRICERATOPS. Our results show a Signal-to-Noise Ratio (SNR) of 294.13 and a False Positive Probability (FPP) of $\approx 0$. Based on the clean spatial environment, stable centroids, and high statistical probability, we validate TOI 7475.01 as a planetary companion. We subsequently performed a Bayesian transit fit using juliet with Dynesty nested sampling, and derived physical parameters via Monte Carlo error propagation. We find a planetary radius of $R_p = 1.18^{+0.39}_{-0.40}\ R_\mathrm{Jup}$ and an equilibrium temperature of $T_\mathrm{eq} = 1455^{+77}_{-56}$ K, consistent with a hot Jupiter classification. The planet mass is estimated at $M_p \approx 2.2\ M_\mathrm{Jup}$ (MAP) via the Chen&Kipping mass-radius relation; radial velocity follow-up is required for a precise measurement. The impact parameter remains unconstrained ($b = 0.46 \pm 0.34$), a limitation of single-band TESS photometry that future CHEOPS observations could resolve.

The low density, hot Jupiter TOI-640 b is on a polar orbit
TOI-640 b是一颗热而膨胀的木星,质量为$0.57 \pm 0.02$ M $_{\rm J}$,半径为$1.72 \pm 0.05$ R $_{\rm J}$,围绕一颗稍微演化的F型恒星运行,距离为$6.33^{+0.07}_{-0.06}$ R $_\star$。通过使用HARPS摄谱仪进行的光谱在途观测,我们测量了Rossiter-McLaughlin效应,分析了在途径向速度和恒星光谱线的畸变。从这些观测中,我们发现主星的投影折射率为$λ=184\pm3^\circ$。从TESS光变曲线中,我们测量了恒星的自转周期,从而确定了恒星倾角$i_\star=23^{+3\circ}_{-2}$,这意味着我们看到的是恒星的极点。结合轨道倾角,我们可以计算出主星的平行度$ψ=104\pm2^\circ$。TOI-640 b加入了一组在$80^\circ-125^\circ$范围内绕恒星两极运行的行星。这种轨道结构的起源还不很清楚。
