The fate of nitrogen during core-mantle separation on Earth Damanveer S. Grewal, Rajdeep Dasgupta, Alexandra K. Holmes, Gelu Costin, Yuan Li, Kyusei Tsuno Nitrogen, the most dominant constituent of Earth’s atmosphere, is critical for the habitability and existence of life on our planet. However, its distribution between Earth’s major reservoirs, which must be largely influenced […]

Science Advances: Delivery of carbon, nitrogen, and sulfur to the silicate Earth by a giant impact

Delivery of carbon, nitrogen, and sulfur to the silicate Earth by a giant impact Damanveer S. Grewal, Rajdeep Dasgupta, Chenguang Sun, Kyusei Tsuno and Gelu Costin Earth’s status as the only life-sustaining planet is a result of the timing and delivery mechanism of carbon (C), nitrogen (N), sulfur (S), and hydrogen (H). On the basis of their isotopic signatures, terrestrial […]
