A Transiting Super-Earth in the Radius Valley and an Outer Planet Candidate Around HD 307842 [PDF]

, 2023
We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial velocity (RV) measurements constrain the mass to be 9.67 ? 0.82 + 0.83 M ? .

A Habitable-zone Earth-sized Planet Rescued from False Positive Status [PDF]

, 2020
We report the discovery of an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649. The planet, Kepler-1649 c, is 1.06+0.15 -0.10 times the size of Earth and transits its 0.1977 ± 0.0051 M⊙mid M-dwarf host star every 19.5 days ...

Asteroid resource map for near-Earth space [PDF]

, 2011
Most future concepts for the exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this required mass from the Earth’s surface increases cost due to the large energy input necessary to move mass out of the ...

TOI-1416: A system with a super-Earth planet with a 1.07d period [PDF]

, 2023
TOI 1416 (BD+42 2504, HIP 70705) is a V=10 late G or early K-type dwarf star with transits detected by TESS. Radial velocities verify the presence of the transiting planet TOI-1416 b, with a period of 1.07d, a mass of $3.48 M_{Earth}$ and a radius of $1 ...

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]

, 2014
We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

A super-earth-sized planet orbiting in or near the habitable zone around a sun-like star [PDF]

, 2013
We present the discovery of a super-Earth-sized planet in or near the habitable zone of a Sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star. We detect two periodic sets of transit signals in the 3-year flux time series of Kepler-69, obtained
