The Orange Dream Project Series: Conceptual, Experimental, and Astrobiological Models
Description
The Orange Dream Project explores an Earth-like planetary model in which biochemistry operates beyond the traditional carbon–oxygen paradigm. Instead, it focuses on phosphorus, arsenic, and silicon as complementary elements capable of forming stable polymers, redox cycles, and structural frameworks for potential life. The project examines planetary chemistry, theoretical biochemistry, and observable biosignatures across three interrelated studies.
— Paper I: Conceptual Planetary Model
Proposes an Earth-like world with moderate temperature and pressure, a semi-oxidizing atmosphere (mainly N₂–CO₂), and oceans enriched in silicate, phosphate, and arsenate compounds. The model demonstrates how phosphorus–arsenic–silicon chemistry could support stable polymeric systems and biochemical energy transfer.
— Paper II: Experimental and Theoretical Biochemistry
Simulated Earth-like conditions (298 K, 1 bar) and UV illumination promote formation of P–Si–O linkages. Theoretical and laboratory analogs suggest that phosphorus–arsenic redox cycles can yield ~40 kJ·mol⁻¹ per reaction, providing a plausible mechanism for non-oxygenic metabolism.
— Paper III: Astrobiological Implications and Observational Signatures
Integrates conceptual and experimental findings into an astrobiological framework. Predicted gases (PH₃, AsH₃, and dimethyl-silane) and surface reflectance features (580–620 nm range) provide identifiable spectral markers for telescopic missions such as JWST, LUVOIR, and ELT.
Together, these three papers constitute the *Orange Dream Project Series*, expanding our understanding of alternative planetary biochemistry and the potential diversity of life beyond Earth.

Abstract (English)
The Orange Dream Project Series presents a unified study of an alternative planetary biochemistry based on phosphorus, arsenic, and silicon under Earth-like environmental conditions.
Paper I introduces a conceptual model of an Earth-analog planet with a semi-oxidizing N₂–CO₂ atmosphere and silicate–phosphate–arsenate oceans capable of supporting P–Si–O polymerization and redox chemistry.
Paper II extends the model through theoretical and experimental simulations demonstrating the energetic feasibility of phosphorus–arsenic redox cycles and the stability of organosilicon–phosphate polymers under 298 K and 1 bar.
Paper III integrates these results into an astrobiological framework, predicting identifiable atmospheric gases (PH₃, AsH₃, Si₂H₆) and surface reflectance signatures (580–620 nm) as biosignatures detectable by future telescopic missions.
Together, the three studies outline a chemically plausible, non-oxygenic biosphere that broadens current definitions of planetary habitability and offers new directions for exoplanet life detection.
