TOI-2498 b: A hot bloated super-neptune within the neptune desert

We present the discovery and confirmation of a transiting hot, bloated Super-Neptune using photometry from TESS LCOGT radial velocity measurements HARPS. The host star TOI-2498 is V = 11.2, G-type (T$_{eff}$ 5905 $\pm$ 12K) solar-like with mass 1.12 0.02 M$_{\odot}$ radius 1.26 0.04 R$_{\odot}$. planet, b, orbits period 3.7 days, has 6.1 0.3 R$_{\oplus}$, 35 4 M$_{\oplus}$. This results in density 0.86 0.25 g cm$^{-3}$. b resides on edge Neptune desert; region mass-period parameter space which there appears to be dearth planets. Therefore an interesting case study further understand origins boundaries desert. Through modelling evaporation history, we determine that over its $\sim$3.6 Gyr lifespan, likely reduced Saturn sized planet current through photoevaporation. Moreover, potential candidate for future atmospheric studies searching species like water or sodium optical high-resolution, carbon based molecules infra-red JWST.
